▼ With the advance of semiconductor and micro-electromechanical systems (MEMS) technologies, ion sensors have been developed from the conventional ion selective electrodes (ISE) to the ion sensitive field effect transistor (ISFET) and extended gate field effect transistor (EGFET) that can be integrated. However, the dimension of the ion detection system is still large because of a commercial reference electrode. To improve this disadvantage, this thesis aims to develop a portable micro sensing chip with integrated AgCl reference electrode for chlorine ion detection. The proposed potable micro chlorine ion sensing chip includes three parts: a Ti/Ag/AgCl electrode chip, a KCl-gel packaging chip and an EGFET-based chloride ion microsensor. Ti/Ag/AgCl electrode chip is fabricated by depositing Ti/Ag membranes on the silicon wafer and then chlorinating the silver membrane by using electrochemical method. KCl-gel packaging chip has two bulk micromachined silicon cavities, one is for filling potassium chloride agarose as a quasi-reference electrode salt bridge and another for external conductor connection. EGFET-based chloride ion microsensor is fabricated by utilizing MEMS technology with a chloride ion selective membrane coated on the extended gate sensing area. A high sensitivity, small size and low cost chloride ion microsensor is developed by integrating AgCl electrode chip, packaging chip and EGFET-based chloride ion microsensor. The total main processing steps of the proposed microsensor includes eight photolithography and eight thin-film deposition processes. The chip size of the proposed portable micro sensing chip with integrated AgCl reference electrode for chlorine ion detection is 1 cm Ã 1.2 cm Ã 0.1 cm, and the sensing area is 0.8 mm Ã 0.8 mm. According to the measurement results, the Ag/Cl reference electrode has a very low and stable offset voltage (1.2 mV in 30,000 seconds). Furthermore, the CV curve of the Ag/Cl reference electrode is same with commercial reference electrode. As the chlorine ion concentration varies from 1Ã10-1 M to 1Ã10-4 M, a very high sensitivity (70 mV/dec) and sensing linearity (0.982) of the chlorine ion microsensor can be demonstrated.

▼ In recent years, the food safety issues have been continuously to occur in the world, such as pesticide residues. The accumulation of pesticide residue in human body via fruits and vegetableâs consumption is likely to cause nervous system disorders, and affect human health. However, if it is possible to develop rapid methods for checking the pesticide residues on fruits and vegetables to be within the maximum residueâs levels of national regulations, prior to consumers eat fruits and vegetables, that can significantly reduce the problem of food security. Presently, the most common pesticide detection techniques are gas chromatograph and liquid chromatograph. Their disadvantages of huge size, high fabrication cost, long detection time and without real-time monitoring function are not conducive to rapid detection. To improve these disadvantages, this thesis aim to develop a rapid EGFET-based pesticides microsensor for organophosphorus and carbamate Detection. In this thesis, an extended-gate field-transistor (EGFET) is developed utilizing micro-electromechanical system (MEMS) technology. Acetylcholinesterase enzyme (AChE) is immobilized by cross-linking method on the extended gate electrode of the EGFET for organophosphorus detection. AuRh bimetallic nanocrystals are selected as the ion selective membrane for carbamate detection because of their ultra-specific responses toward carbamate pesticides. The main processing steps of the EGFET device in this study involve four photolithographic and four thin-film deposition processes, as well as two photolithographic and two thin-film deposition processes to fabricate the packaging chip. The size of the proposed EGFET-based pesticides microsensor is 12 mm Ã 10 mm Ã 0.5 mm and the sensing area is 0.8 mm Ã 0.8 mm. Based on the measurement results of the pesticides microsensors, the sensitivity, sensing linearity and response time of the organophosphorus microsensor are 37.5 mV/dec, 0.985 and 300 sec, respectively, as the sensing pesticides concentration varies from 0.001 ppm to 10 ppm. At the same situations, the carbamate (68.0 mV/dec, 0.982 and 120 sec) were also presented in this paper.

▼ According to the report of Health Promotion Administration, Ministry of Health and Welfare, prostate cancer is the sixth leading cause of cancer death in Taiwanese men in 2016. Prostatic Specific Antigen (PSA) is a very important serum of prostate disease. It can be used in the clinical diagnosis of prostate cancer, but also can detect and track the effect of postoperative treatment. Although conventional PSA detectors have high sensitivity and accuracy, their disadvantages of expensive testing chemicals, long detection time and huge size are not suitable for point of care testing (POCT) application. For this reason, this thesis aims to develop a flexural plate-wave (FPW) based PSA biosensor for POCT application. FPW device was fabricated by utilizing micro-electro mechanical systems (MEMS), the main fabrication steps include seven thin-film depositions and five photolithography processes. To accurately control the thickness of the silicon thin-plate and substantially improve the fabrication yield of FPW transducers, a two-step anisotropic wet etching process was developed. Furthermore, by using cystamine-based self-assembled monolayer (SAM) nanotechnology, we used the proposed FPW device to develop a novel FPW-based PSA biosensor for prostate cancer detection. The influence of the geometries and structures of the interdigital transducers (IDTs) and reflective grating structures (RGS) on the insertion loss of FPW device are investigated in this thesis. According to the measurement results, FPW device with circular-type IDTs and silicon groove RGS has the lowest insertion loss (-38.158 dB). However, FPW device with parallel-type IDTs and silicon groove RGS has the highest mass sensitivity (100.955 cm2/g). The detection limit and sensing linearity was measured under six different concentrations of the PSA antigen (2.5, 5, 10, 20, 40 and 80 ng/mL) coated on the backside cavity of the FPW-based PSA biosensor. Under the optimized condition, a low insertion loss (-38.158 dB), very low detection limit (2.5 ng/mL) and high sensing linearity for PSA concentration 1~10 ng/ml and 10~80 ng/ml (0.999, 0.995) can be obtained.

▼ Since the Internet of Things (IoT) and Internet of Vehicle (IoV) markets are increasing rapidly, the wireless communication system with higher data rate, information accuracy and farther transmission distance are developed for matching the requirements of the multi-input multi-output (MIMO) techniques. However, there are similar passive and active devices with the same functions consume extra area in the MIMO receiver system. In order to improve the disadvantage, this thesis designed and developed a multiplex power divider replaced two traditional power dividers utilizing the surface micromachining process, and diminish the dimensions of divider for the needs of wireless communications network products. To realize the power divider with four-phase outputs, low transmission losses and compact size characteristics, the main fabrication processes in this thesis including: (i) Employ two central tapped power divider to reduce the chip size; (ii) Utilize suspended structure to reduce the insertion loss caused by parasitic capacitance between device and substrate; (iii) High dielectric constant material (zirconium oxide) used as the dielectric layer to significantly reduce dimension. This power divider constructed of bottom electrode, supporting posts and top electrode. The main fabrication processes including six thin-film depositions, three copper electroplating, five graphic definitions of photolithography and four etching processes. Compared with our previous research (Chia-Lung Song, senior, 2016). The chip size is significantly reduced from 2900 Î¼m (L) Ã 2800 Î¼m (W) Ã 21 Î¼m (H) to 1290 Î¼m (L) Ã 1060 Î¼m (W) Ã 24.15 Î¼m (H), the reduction range is about 593%. The multiplex power divider with 2.4 GHz operating frequency and measured from 10 MHz to 8.0 GHz by network analyzer. There were two generations of the power divider in this thesis. The initial generation with double-layer capacitance showed the four output insertion losses are -71.10, -57.25, -50.83 and -71.33 dB, and -10.89, -12.27, -8.98 and -15.98 dB in the subsequent generation with single-layer capacitance, all the output insertion loss characteristics improved above than 78%. Moreover, the input return losses enhanced from -0.34 and -0.32 dB to -1.34 and -1.17 dB, which improved 294% with early. The output return losses demonstrate -0.82, -0.84, -0.87 and -0.69 dB in the previous generation, and -1.51, -2.09, -7.25 and -2.18 dB in the following generation, which enhanced more than 84%. Compare with the standard phase difference (180Â°), the initial generation exhibited 87.99Â° and 61.42Â°, whereas 9.93Â° and 0.50Â° in the subsequent generation.

▼ As working time increases for most people, dining out and staying up late is inevitable, resulting in bad health condition. The concentration of sodium, calcium, ammonium and chloride ion in human blood not only respond directly to health condition, but can also obtain symptoms of different disease by observing it. This shows that the concentrations of sodium, calcium, ammonium and chloride ion in human blood are an important index of health. In this thesis, an extended-gate field-transistor (EGFET) is developed utilizing micro-electromechanical system (MEMS) technology. Then the gate metal electrodes of the EGFETs are coated with ion selective membranes (ISMs) which can adsorb and measure the appointed ions to develop the sodium, calcium, ammonium and chloride ion microsensors in one chip. The main processing steps of the EGFET in this study involve four photolithographic and two thin-film deposition processes, as well as two photolithographic and two thin-film deposition processes to fabricate the package chip. The influence of the channelâs width/length ratio, the design of channelâs figure, the sensitivity of the applying sensitive membrane and selectivity of the sensitive membrane were investigated, after that the best performance of the channelâs width/length ratio and channelâs figure design could be obtained. he chip size of the extended gate field effect transistor microsensor is 11 mmÃ13 mmÃ0.5 mm and the sensing area is 1 mmÃ1 mm. Based on the measurement results of the ion sensors, the sensitivity and sensing linearity of the sodium ion microsensor are 58 mV/pNa and 99%, respectively, as the sensing ion concentration varies from0.1mM~0.1M . At the same situations, the calcium ion (40 mV/pCa and 93%), the ammonium ion (41 mV/pNH 4 and 98.4%) and the chloride ion (58 mV/pCl and 96%) were also presented in this paper.

▼ The IEEE 802.11a has become the mainstream protocol used in modern wireless communication system due to its high propagation rate of data (54 Mb/s). In order to keep RF receiver to operate at linear region under receiving strong signal, the gain of low noise amplifier must be tunable to avoid influencing the subsequent block. Traditional variable gain low noise amplifier is mainly adopted in cascade. Owing to the cascade includes amplifier, attenuator and buffer stages, the more complexity and power consumption increased. This thesis utilizes dual stage to simplify complexity of the circuit and variable gain low noise amplifier fabricated in TSMC 0.18 Âµm CMOS technology for IEEE 802.11a application. Without sacrificing gain, the variable gain low noise amplifier employ current-reuse structure to amplifier stage to reduce power consumption, variable-impedence structure to load stage to achieve variable gain, source follower structure to buffer to improve output matching, N-type diode load and source-degeneration structure to input stage to improve input matching. The proposed variable gain low noise amplifier with 1.1 mm Ã 1.1 mm chip size and its 5.2 GHz operating frequency is well suited for IEEE 802.11a (5~6 GHz) application. Measurement resutls demonstrate the highest and lowest gain of 15.29 and 8.19 dB respectivly, the gain tuning range is approximated as 7.1 dB. Moreover, the amplifier shows input return loss of -16.17 dB (highest gain mode)/-15.2 dB (lowest gain mode) and very good output return loss of -17.22 dB (highest gain mode)/-19.1 dB (lowest gain mode). Simultaneously, the amplifier shows isolation of -39.42 dB (highest gain mode)/-38.72 dB (lowest gain mode). Finally, a moderate consuming power are 16.05 mW (highest gain mode)/15.3 mW (lowest gain mode) of such varible gain low noise amplifier can be achieved from 1.6 V supply voltage.

▼ ããIn recent years, high carbon dioxide emissions not only result in serious air pollution and greenhouse effect, but also cause water acidification and decrease the survival rate of fry in aquaculture. Therefore, to develop a high-quality sensing system for real-time detecting the concentration of carbon dioxide in water is a very important research topic. The conventional carbon dioxide detectors in water have caused the detection inconvenient because of their large dimension, high fabrication cost and without real-time monitoring function. To improve these disadvantages, this thesis aims to develop a carbon dioxide microsensor integrated with an all-solid-state micro reference electrode. ããThis thesis utilizes micro electro mechanical systems (MEMS) technology to develop micro reference electrode including electrode chip and packaging chip. One wafer of this module is defined as electrode chip. It has titanium/silver membranes deposited on the silicon wafer and then chloridizes the silver membrane by using electrochemical method. So it is namely silver/silver chloride quasi-reference electrode. Another wafer is called as packaging chip and it has two bulk micromachined silicon cavities for filling potassium chloride agarose as a quasi-reference electrode salt bridge and another for external conductors connection. Next, the thesis implements an extended gate field effect transistor (EGFET) with gas permeable membrane and solid electrolyte membrane for development of a high sensitivity, small size and low cost carbon dioxide microsensor. The total main processing steps of the proposed microsensor includes six photolithography and nine thin-film deposition processes. In addition, the influences of the filling cavity size of micro reference electrode and the channel width/length ratio of EGFET on the sensing performances of presented microsensor are also investigated in this study. ããThe chip size of the implemented micro reference electrode is 9 mmÃ6 mmÃ0.5 mm. It has a very low and stable offset voltage (-3.0 mV in 30,000 seconds). Furthermore, a CV curve of the packaged reference electrode is same stable with commercial reference electrode. Also, the chip size of the implemented carbon dioxide microsensor with micro reference electrode is 3 cmÃ2 cmÃ2 mm and the sensing area is 1 mmÃ1 mm. As the carbon dioxide concentration varies from 0.25 mM to 50 mM, a very high sensitivity (44.4 mV/dec) and sensing linearity (98.37%) of the proposed EGFET microsensor can be demonstrated. In addition, the response time of the presented carbon dioxide microsensor is only about 100 seconds. Therefore, this thesis proves a carbon dioxide micro gas sensor with integrated micro reference electrode has three advantages such as small dimension, low fabrication cost and real-time monitoring function.

▼ Due to the increasing percentages of traffic accidents in our society, many automobile manufacturers devote to develop various automotive anti-collision radar warning systems. Utilizing these radar warning systems, drivers can make some responses for preventing accident occurring within few seconds. However, for the automotive collision avoidance radar receivers, low-noise amplifiers must have the abilities of highly stable and amplify the signal to ensure the messages are shown perfectly and accurately, which give motorists attentions of traffic accident. To achieve the above characteristics, the traditional low-noise amplifiers consume greater power to meet the high-gain and stable functions. Therefore, this thesis employs the TSMC 0.18 Î¼m CMOS process to develop low-noise amplifiers designs with both high gain and low power consumption which can be implemented in automotive anti-collision radars. This thesis utilizes dual stage to simplify complexity of the circuit without sacrificing the power consumption. In order to effectively increase the gain and stability, the proposed low-noise amplifiers comprises a negative resistance of a gm-boosted technology, the concept of zero-pole point, the paralleled RC structure, a source follower buffer and a source-degeneration structure employed into the input stage improving input matching. The proposed low noise amplifier with 1.4 mm Ã 0.7 mm chip size and its 24 GHz operating frequency is well suited for automotive radar (22-29 GHz) application. This low noise amplifier shows a very high-gain of 21.2 dB. Moreover, the amplifier presemts input return loss of -18.1 dB, very good output return loss of -28.1 dB and excellent isolation of -65.6 dB. Finally, a moderate consuming power are 15.8 mW of low noise amplifier from 1.5 V supply voltage.

▼ Acoustic micro-sensors have already been applied in mass sensing including surface acoustic wave (SAW), thickness shear mode (TSM), shear horizontal acoustic plate mode (SH-APM) and flexural plate wave (FPW). The conventional FPW device has advantages of high mass sensitivity, low phase velocity and low operation frequency. However, conventional FPW devices usually present a high insertion loss and low fabrication yield. The main contribution of this thesis is introduced a novel circular-arc interdigital transducers (IDT) into FPW device for efficiently reduce the high insertion loss of conventional FPW device. The major technology utilized in this study is bulk micromachining technology and the main fabrication steps include seven thin-film deposition and five photolithography processes. This thesis develops a length of delay line which is fixed at 250 Î¼m and 15-pair IDTs with five kinds of difference FPW devices: (i) Type A : circular-arc IDT and without Focus-type reflective grating structure (RGS) (ii) Type B-D : circular-arc IDT with 6/8/10-pair RGS (iii) Type E : parallel-type IDT with 10-pair RGS. Measurement results demonstrate the insertion loss of above five different FPW devices are -45.634 dB, -41.651 dB, -40.202 dB, -37.070 dB and -46.865 dB respectively. It proves that the circular-arc IDT has better energy aggregation effect than parallel design. By comparing with the measured results of type D and type E FPW device, the insertion loss of type D is less than that of type E FPW device. Therefore, the circular-arc IDT design can efficiently reduce the insertion loss of FPW device. Finally, as the five aluminum membranes the thickness of each layer is (1000 Ã) were evaporated on the bottom surface of back side cavity, the mass sensitivity and sensing linearity of the presented FPW devices are 11.54 cm2/g and 96.69 % respectively.

▼ According to the World Cancer Report 2014 by the International Agency for Research on Cancer (IARC), the global number of cases of colorectal cancer increased from 1.23 million in 2008 to 1.4 million in 2012. The colorectal cancer has also become the third major cancer killer in Taiwan. Carcinoembryonic Antigen (CEA) is a common tumor markers, which is secreted and released into the blood by the tumor cells. When the tumor cells form, the concentration of CEA will also increase in the blood. Currently, the main purpose of CEA in clinical is to keep tracking and detecting of colorectal cancer. However, the traditional CEA detectors usually have disadvantages of huge size, high cost, long detection time, etc. In order to detect colorectal cancer rapidly, a flexural plate-wave (FPW) biosensor for detecting CEA is developed in this thesis. A FPW transducer was fabricated using micro-electro-mechanical systems (MEMS) technologies. The main fabrication steps of the proposed FPW devices include seven thin-film depositions and five photolithography processes. To accurately control the thickness of the silicon thin-plate and substantially improve the fabrication yield of FPW transducers, a two-step anisotropic wet etching process was also developed. Furthermore, by using cystamine-based self-assembled monolayer (SAM) nanotechnology, we used the proposed FPW device to develop a novel FPW-based carcinoembryonic antigen (CEA) biosensor for detection of colorectal cancer. The implemented FPW device with dimension only about 0.56Ã0.56 cm2 and the thickness of suspended silicon plate can be accurately controlled to 20 Î¼m. Under the optimized conditions, a very low insertion loss (-38.652 dB), very high mass sensitivity (126.67 cm2 /g) and high fabrication yield (60.78%) can be obtained. Furthermore, the proposed FPW based CEA-biosensor demonstrated a very low detection limit (5 ng/mL) and high mass-sensing linearity (0.96).

▼ The conventional coupler realized by utilizing CMOS process with stacked structure, this stacked layers will increase the insertion loss due to the parasitic capacitance and lossy substrate in radio-frequency. Except the CMOS process, there are also couplers with four-phase output characteristic implemented in Monolithic Microwave Integrated Circuit (MMIC) manufacturing process. However, MMIC couplers are difficult to integrate with ICs since it consumes larger area[1]. In order to overcome the above mentioned issues, this thesis proposes the suspended four-phase output coupler using Micro-Electro-Mechanical Systems (MEMS) process to enhance the insertion loss and reduce the dimension of the traditional coupler. To achieve the four-phase coupler with low insertion loss, four-phase output and high isolation characteristics, the main fabrication processes in this thesis including: (i) Utilize suspended structure to enhance the insertion loss caused by parasitic capacitance between device and substrate; (ii) Use the air dielectric layer of MIM capacitors for input/output ports matching; (iii) Construct of a tandem coupler with center-tapped baluns to perform four-phase output, and optimize the analysis of the coupler by employing high frequency simulation software (HFSS and ADS. The suspended four-phase coupler constructed of supported posts, bottom and top electrodes and vias. The main fabrication processes including four thin-film depositions, four photolithography, four copper electroplating and etching processes. Our previous research (Wen-Hong Hsu, senior, 2014) had developed a first-generation four-phase coupler using MEMS surface micromachining process with dimensions of 22 mm (W) Ã 12.8 mm (L) Ã 71 Î¼m (H); under the similar processing conditions, the second-generation of suspended four-phase coupler in this thesis is significantly smaller than first-generation one with size of 9.5 mm (W) Ã 6.4 mm (L) Ã 36 Î¼m (H). Compare the characteristic of insertion loss with the first-generation, which enhanced from -45.0, -47.9, -49.8 and -51.6 dB, to -18.74, -20.14, -24.10 and -22.23 dB, is approximately 56% improvement of insertion loss. Input return loss of -4.53 dB is improved to -16.20 dB, which shows characteristic of reflection loss boosting about 3.5 times. In addition, compared to the standard phase difference (180Â°), the output of two-port phase difference respectively improved from 16.1Â° and 21.1Â° to 1.2Â° and 4.7Â°.

▼ Since the Internet of Things (IoT) and Internet of Vehicle (IoV) markets are increasing rapidly, the wireless communication system with farther transmission distance, higher data rate and information accuracy are developed for matching the requirements of the multi-input multi-output (MIMO) techniques. However, there are similar passive and active devices with the same functions consume extra area in the MIMO receiver system. In order to improve the above drawback, this thesis designed and developed a multiplex power divider replaced two traditional power dividers utilizing the surface micromachining process, and diminish the dimensions of divider for the needs of wireless communications network products. To optimum the performances of power divider, this thesis uses the commercial software ANSYS HFSS and Agilent ADS to analyze and extract high-frequency characteristics. The main structures in this thesis including: (i) Employ two central tapped power divider to reduce the area; (ii) Utilize suspended structure to reduce the insertion loss caused by parasitic capacitance between device and substrate; (iii) Use epoxy negative resist (SU-8 5) as a MIM capacitor dielectric layer to enhance the returns. This power divider constructed of bottom electrode, supporting posts and top electrode. The main fabrication processes including six thin-film depositions, five graphic definitions of photolithography, three copper electroplating and four etching processes.

▼ In the last decade,various structural designs and sensing mechanisms of ion sensors have been widely used in industrial,environmental monitoring and biomedical areas.However,the sensing characteristics of those ion sensors are obviously affected by the temperature of testing solution and therefore results in wrong readouts.To improve this issue,this thesis devoted to develop an extended-gate field-effect transistor(EGFET) based micro ion sensors with temperature compensation and calibration functions.The output characteristics of the presented EGFET ion sensors are measured under different temperatures (20â~50â) and various hydrogen ion concentrations (pH2~pH10). This thesis utilizes micro-electromechanical systems (MEMS) technology to develop EGFET-based micro ion sensors.The signal readout circuit is built by four components:bridge readout circuit,temperature sensors,temperature calibration circuit and differential temperature compensation circuit.The EGFET-based micro ion sensor and the signal readout circuit are combined to form the EGFET-based ion sensor with temperature compensation and calibration functions.The main processing steps of the EGFET in this study involue four photolithographic and two thin-film deposition processes.The influence of output characteristics before and after the temperature compensation,and the temperature range of compensation could be obtain in this study. The chip size of the EGFET microsensor is 11 mm Ã 13 mm Ã 0.5 mm and the sensing area is 1 mm Ã 1 mm.The temperature range of the measured standard buffer solution is from 20â to 50â,and the various hydrogen of the standard buffer solution is from pH2 to pH10.The measured results show that the temperature compensation circuit has excellent compensation effect under 20â~45â, respectively,without temperature compensation.After temperature compensation,the average error the various hydrogen have become 12.71% and 15.43% under 20â and 45â,respectively,without temperature compensation.After temperature compensation, the average error of the various hydrogen have become 8.16% and 11.38% under 20â and 45â,respectively.The temperature compensation and calibration circuit in this study has significantly reduce the error of the signal readout characteristic.

▼ Water resource is one of the most important natural resources on earth. In recent years, due to the discharges of large industrial and domestic waste-water into the nature, water pollution problem is getting more and more serious and how to monitor the quality of water in real time has become a very important research issue. The dissolved oxygen is one of the critical indexes for evaluating the quality of water. Although the conventional dissolved oxygen detectors presented a high sensitivity and high accuracy, the high cost, large dimension, low capability of batch fabrication and real-time monitoring will limit their applications. In this thesis, an extended-gate field-effect transistor (EGFET) based dissolved oxygen microsensor is developed utilizing micro-electromechanical system (MEMS) technology. The gate voltages of EGFET under different concentrations of dissolved oxygen can be detected by the Cr/Au sensing electrode. To further enhance the sensitivity of the proposed microsensor, a polystyrene layer with very high permeation rate of the dissolved oxygen gas is adopted and coated on the surface of Cr/Au layer. The main processing steps of the presented microsensor involve four photolithographic and four thin-film deposition processes. The influence of the channelâs width/length ratio, source/drain geometry and polystyrene additional layer on the sensitivity of the EGFET based dissolved oxygen microsensor are investigated in this study. The chip size of the implemented dissolved oxygen microsensor is 11 mmÃ13 mmÃ 0.5 mm and the sensing area is 1 mmÃ1 mm. As the dissolved oxygen concentration varies from 2 ppm to 6 ppm, a very high sensitivity (35.36 mV/ppm) and sensing linearity (98.83%) of the proposed EGFET microsensor can be demonstrated. In addition, the response time of the presented dissolved oxygen microsensor is only about III 180~200 seconds, hence it is very suitable for developing a real-time monitoring microsystem.

▼ Abstract Compared with the other micro acoustic wave devices, the flexural plate-wave (FPW) device is more suitable for being used in liquid-sensing applications due to its higher mass sensitivity, lower phase velocity and lower operation frequency. However, conventional FPW devices usually present a high insertion loss and low fabrication yield. To reduce the insertion loss and enhance the fabrication yield of FPW device, a 1.5 Î¼m-thick silicon-trench reflective grating structure (RGS), a high electromechanical coupling coefficient ZnO thin-film and a 5 Î¼m-thick silicon oxide membrane substrate are adopted in this research. The influences of the amount of silicon trench and the distance between inter-digital transducer (IDT) and RGS on the insertion loss and quality factor of FPW device are investigated. The main fabrication technology adopted in the study is bulk micromachining technology and the main fabrication steps include six thin-film deposition and five photolithography processes. Under the optimized conditions of the sputtering deposition processes (200â substrate temperature, 200 W radio-frequency power and 75% gas flow ratio), a high C-axis (002) orientation ZnO piezoelectric thin-film with 31.33% electromechanical coupling coefficient can be demonstrated. The peak of XRD intensity of the standard ZnO film occurs at diffraction angle 2Î¸ = 34.422Â°, which matches well with our results (2Î¸ = 34.282Â°). By controlling the thickness of ZnO/Au/Cr/SiO2/Si3N4 sensing membrane less than 6.5 Î¼m-thick, the fabrication yield of FPW device can be improved and a low operation frequency (6.286 MHz) and high mass sensitivity (-113.63 cm2 / g) can be achieved. In addition, as the implemented FPW device with four silicon trenches RGS and 37.5 Î¼m distance between IDT and RGS, a low insertion loss (-40.854 dB) and very high quality factor (Q=206) can be obtained.

▼ The conventional flexural plate-wave (FPW) device has advantages of high mass sensitivity, low phase velocity and low operation frequency. However, conventional FPW devices usually present a high insertion loss and low fabrication yield. This thesis aimed to reduce the insertion loss of conventional FPW devices. The influences of geometry of inter-digital transducers (IDTs), pair number of IDTs, depth of focus and length of delay line on the insertion loss of FPW device are investigated. This research utilizes bulk micromachining technique to develop a low insertion-loss FPW device and the main fabrication steps include seven thin-film deposition and four photolithography processes. As the wavelength is 100 Î¼m, pair number of IDTs is 20, depth of focus is 1000 Î¼m and length of delay line is 500 Î¼m, the measured insertion loss of the implemented FPW device with conventional parallel-type IDTs and novel focus-type IDTs are equal to -48 dB and -45.06 dB, respectively. On the other hand, the insertion loss of FPW device with focus-type 25-pairs IDTs (-43.69 dB) is smaller than that of FPW device with focus-type 20-pairs IDTs (-45.06 dB). Additional, the measured insertion loss of FPW device with 500 Î¼m focus depth (-41.47 dB) is smaller than that of FPW devices with 1000 Î¼m focus depth (-43.69 dB) or with 1500 Î¼m focus depth (-45.39 dB). Furthermore, the FPW device with 500 Î¼m delay line presents a smaller insertion loss (-40.46 dB) than that of FPW devices with 250 Î¼m delay line (-41.47 dB) or with 750 Î¼m delay line (-40.95 dB). Finally, under the optimized specifications (focus-type/25 pairs IDTs, 500 Î¼m focus depth and 500 Î¼m delay line), the FPW-based microsensor demonstrates a high sensitivity (91.53 cm2/g), high sensing linearity (99.18 %) and low insertion loss (-40.46 dB), hence it is very suitable for development of biomedical sensing microsystem.

▼ The IEEE 802.11a has become the mainstream protocol used in modern wireless communication system due to its high propagation rate of data (54 Mb/s). To meet high propagation rates, the communication devices used in IEEE 802.11a protocol usually present a high conversion gain and a high linearity (denoted as third order intercept point, IIP3). The IIP3 of conventional up- and down-conversion mixers are only about 0 dBm and -5 dBm, which fail to achieve a high propagation rate of data. This thesis utilizes the TSMC 0.18 Î¼m CMOS technology to design and fabrication up- and down-conversion mixers with very high linearity for IEEE 802.11a application. The proposed high-linearity up-conversion mixer with 1.01 mm Ã 0.85 mm chip size and its wide bandwidth (5~6 GHz) is well suited for IEEE 802.11a application. To enhance the linearity and bandwidth, a transconductor stage with gm-boosted structure, a switch stgae with LO-body grounded structure and a load stage with shunt peaking structure are adopted in this research. Under 5.2/5.4/5.8 GHz operating frequencies, the implemented up-conversion mixer demonstrates a high conversion gain of 6.8/7.1/6.3 dB and a high linearity of 8.9/9/13.2 dBm, respectivly. In addition, a moderate consuming power (6.86 mW) of such mixer can be achieved at 1.2 V supply voltage. On the other hand, this thesis also designed and fabricated a high-linearity down-conversion mixer with chip size of 1.02 mm Ã 0.86 mm and 5.2 GHz center frequency. To improve the linearity and isolation and reduce the high-order noise, a transconductor stage with dual-gate structure and a load stage with RC-tank structure are adopted in this research. According to the EM-simulation resutls, the proposed down-conversion mixer presents a moderate conversion gain of 6 dB and a high linearity of 0.8 dBm. Additionly, a moderate consuming power (6.75 mW) of such mixer can be achieved at 1.8 V supply voltage.

▼ Since the global mobile communication systems and the wireless multimedia markets are increasing rapidly, various innovative electronic devices or circuits with higher transmission bandwidth, lower delay time and high-speed data rate are developed for matching the requirements of the new-generation global mobile communication products (Long Term Evolution, LTE). However, for providing higher power conversion gain, the new-generation receiver chip will consume larger power than that of 3G products. In this thesis, a wide-band (0.5~2.8 GHz) front-end receiver with high power conversion gain (â¥ 15 dB), high linearity (â¥ -10 dBm), low input insertion loss (â¤ -15 dB), low noise figure (â¤ 10 dB) and low power consumption (â¤ 40 mW) are developed utilizing TSMC 0.18 Î¼m CMOS technology and which can be used in 4G mobile network system. The proposed receiver chip is including a low noise amplifier (LNA), a variable gain amplifier (VGA) and a down-conversion mixer. The conversion gain, power consumption and bandwidth of the receiver can be improved by using self-biasing inverter and feedback resistor architectures. In addition, a source degeneration technique and RC-tank load are adopted in the proposed mixer to enhance the linearity and suppress high frequency signal, respectively. The chip size and operation frequency of the implemented receiver were 1.2 Ã 1.0 mm2 and 0.5~2.8 GHz, respectively. Under the optimized conditions, a high conversion gain (31.2 dB), high linearity (the Input third-order Intercept Point, IIP3 =-6.1 dBm), low input return loss (-20.1 dB), high reverse isolation (-72 dB) and low noise figure ranges (4.2 dB) and low power consumption (20 mW, at 1.8 V supply voltage) of the presented receiver chip can be demonstrated in this research and such characteristics are well suitable for 4G mobile communications system applications.

▼ According to the 2014 annual report of Health Promotion Administration (Ministry of Health and Welfare, Taiwan), the hepatocellular carcinoma (HCC) has become the second major cancer killer in Taiwan. Usually, the concentration of alpha fetoprotein (AFP) in human serum can be detected by various commercial sensing equipment (> 40Ã30Ã10 cm3) and be used for the initial stage diagnosis of HCC. Various flexural plate-wave (FPW) micro biosensors and related bio-sensing microsystems (25Ã10Ã5 cm3) have been developed for POCT (Point-of-Care Testing) applications in our previous researches. However, the conventional FPW devices have two major disadvantages of high insertion loss (> 40 dB) and low fabrication yield (< 10%) which will limited their commercialization. To improve effectively the insertion loss and fabrication yield of FPW device, a small-size interdigital transducer with circular-arc geometry design, two different rate of silicon anisotropic etching process and a high C-axis ZnO piezoelectric thin-film deposition process are developed in this thesis. The main fabrication steps of the proposed FPW based on AFP-biosensor including seven thin-film depositions and five photolithography processes. Two major technologies used in this work are micro-electro-mechanical systems (MEMS) technology and cystamine based self-assembly monolayer (SAM) nanotechnology. The implemented FPW device with dimension only about 0.7Ã0.9 cm2 and the thickness of suspended silicon plate can be accurately controlled to 20 Î¼m. Under the optimized conditions, a very low insertion loss (-36.04 dB), very high fabrication yield (64.81%) and high mass sensitivity (70.06 cm2/g) can be obtained. Furthermore, the proposed FPW based AFP-biosensor demonstrated a very low detection limit (5 ng/mL) and high mass-sensing linearity (0.9304).

▼ According to the report by the World Health Organization (WHO), cardiovascular disease is the number one killer of global deaths. An estimated 17.7 million people died from CVDs in 2015, representing 31% of all global deaths. When cardiomyocytes are damaged or killed, important components in the cell, such as troponin T and troponin I, are released outside the cell and can be detected in the blood. In order to diagnose early, this thesis aim to develop a rapid extended gate field-effect-transistor (EGFET)-based microsensor for cardiac troponin detection. In this research, the EGFET-based cardiac troponin microsensor is developed by micro-electromechanical process technology, which includes three parts: silver/silver chloride quasi-reference electrode, extended gate field effect transistor and potassium chloride gelatin package wafer. The main processing steps of the implemented microsensor in this study involve eight photolithographic and eight thin-film deposition processes. Honeycomb and parallel geometry patterns of the extended gate electrodes with four different size are designed to investigate their impact on the sensitivity. Finally, the combined method immobilizes the cardiac troponin antibody on the extended gate and detects the potential difference of the antibody antigen bond. The size of the miniature cardiac troponin sensor developed in this paper is 14.1 mm Ã 7.5 mm Ã 10 mm. The optimal extended gate is honeycomb geometry pattern with 2.0 mm Ã 2.0 mm sensing area. Based on the measurement results, the minimum detection limit, sensitivity, sensing linearity and hysteresis voltage are 0.0125 ng/mL, 214 mV/dec, 0.974 and 1.51 V, respectively, as the concentration of the test solution varies from 0 ng/mL to 0.1 ng/mL. The EGFET-based cardiac troponin microsensor developed in this paper has the advatages of small volume, low detection limit, high sensitivity, high linearity and fast response time.
