1. Chen, You-Yi. Simulation and Analysis of 3D IC Through Silicon Vias (TSVs) Arrays under High-Frequency Electromagnetic Fields.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2014, NSYSU

This study consists of two parts. First part is about the through via in printed circuit board (PCB). In the PCB, signal transmission between different layers occurs by way of through via. The excessive capacitance is generated near the through via. Such capacitance influences the signal transmission between different layers. Through via also cause return current path discontinuous. It excites parasitic transverse electromagnetic modes in PCB. Both excessive capacitance and return current path discontinuous cause the power loss. Some techniques solving this problem are discussed. Finite element method (FEM) is used to simulate the high frequency electromagnetism and extract the S-parameters. S-parameters are used to describe the electrical behavior of through via. By these model, we want to predict the signal transmission performance of the through via structure. Second part is about through silicon via (TSV). TSV which is used to connect stacked chips in a vertical fashion become the heart of this technique, because there are big signal attenuation in the wire bonding approach and large solder balls in the ï¬ip-chip. When a high frequency signal is transmitted vertically through the substrate via, low resistivity silicon substrate will cause significant signal attenuation and lead poor ratio frequency (RF) performance. 3D electromagnetic field solver is employed to build up finite element models. Equivalent circuit model is also used to simulate the electrical performance of TSV. The impact of different TSV shapes and materials on electrical performance is evaluated by using S-parameters. By these models, we want to propose an accurate finite element model to predict electrical performance of TSV and easily design 3D IC integration for designer.

2. Wang, Yung-Wen. Thermo-mechanical Finite Element Model in BGA Solder Joints Fatigue Life Analysis.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2014, NSYSU

As the microelectronic package develops technologies for fabrication smaller, faster and economical, thermal management play an important role. Temperature variation caused by either environmental changes or power consumption, and the coefficient of thermal expansion (CTE) mismatch between different packages material lead to stress and strain in package assemblies especially in solder joint. This research builds up the viscoplastic finite element model to analyze thermal-mechanical behavior of solder joint under temperature cycling loading. The finite element software ANASYS is used to calculate the accumulative strain energy density of solder joint. Furthermore, a design of experiment (DoE) with factorial analysis is used to investigate the reliability impact of the design parameters, including solder material properties and geometry. Finally, we use the analysis of variance (ANOVA) to obtain the regression model and to find out optimization factors. The purpose of this research is to provide a quickly experimental design assessment to improve reliability of the solder joint. The assessment model can be used to predict the accumulative strain energy density and fatigue life of the solder joint in terms of cycles to failure. The smaller plastic strain can be achieved through a better combination of material properties and geometry parameters, which is helpful of packaging design before to manufacturing.

3. Wang, Ming-Han. Stress and Warpage Analyses on the 3D and 2.5D ICs with TSV Structure under Thermal and Moisture Effects.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2014, NSYSU

Polymer material tends to absorb moisture of environment to cause volume swelling among various materials of electronic package, such as underfill and substrate. The residual moisture of the package would also be vaporized into vapor phase in the reflow process. These phenomena render expansion mismatch and stress concentration at the interface between each components. If stress induced by moisture, vapor pressure and temperature up to mechanical strength, the product have the risk to damage and affect the operation. This paper adopt the finite element software, ANSYS v14.5, to investigate moisture diffusion and structure effects of hygro-thermal-vapor pressure coupling. This study is divided into two parts: First part is about 3D IC package. Second part is about 2.5D IC package. In 3D IC research, whether the mold compound covered and through silicon vias, micro-bumps are discussed under moisture, vapor pressure and temperature effects. In 2.5D IC research, the traditional inorganic passivation layer, Si3N4, is analyzed, in addition, the low-cost organic material is also investigated. Besides, the material properies of organic material will have a sharply change after reflow temperature up to the glass transition temperature (Tg). This paper also focus on this issue and compare the results of these two advanced package under hygro-thermal-vapor pressure coupling.
