▼ To solve the problem of limited deformation in metallic glass, newly ternary or quaternary alloy systems have developed the second phase within an amorphous matrix in recent years. These alloy systems have second-phase particles or nanocrystals in a glassy matrix, phase-separated regions, and variations in short-range order by clustering. The second phase within an amorphous matrix can produce the amorphous/amorphous, amorphous/short-range order or amorphous/crystalline composite structure, depending on its glass-forming ability (GFA). Investigating the possibility for the design of a new type of composite structure (i.e., amorphous/crystalline or amorphous/short-range order composites instead of amorphous/amorphous composites) may be able to improve the ductility of BMG. This study presents a newly designed Zr-based alloy (Zr63.36Cu17.22Ni11.47Al7.95) in Zr-Cu-Ni-Al phase separation system based on thermodynamic-computation approach, and describes its microstructure and crystal structure with different cooling rates. It can obtain completely amorphous structure, the amorphous/ short-range order and the amorphous/ crystalline composite structure by fast to slow cooling rate. Although the experimental result was no phase separation phenomenon as expected, but it was surprisingly that forming the dual phase composite structure with short-range order droplet phase and amorphous matrix phase. And it was interesting that the average compositions of the droplet-type phase and amorphous matrix phase were identical within experimental error. It means that no local primary nucleation and growth was occurring during solidification process, so that the compositions of droplet phase are the same as the compositions of matrix amorphous phase. In order to understand the same chemical composition but have different image contrast, that we use XRD, EBSD and TEM analysis to understand whether they caused by different degrees ordered structure. The results show that there are three different short-range order structures in droplet-type phase. Therefore, it contributes to the weak crystallization signals and the structure is different from the amorphous matrix phase. Finally, we use the heat treatment in order to understand the relationship between the droplet phase, the matrix phase and equilibrium phase. The results show that the Zr2Ni(Al,Cu)-type phase of cubic structure is a metastable phase and it will occur phase transformation at 686 K in the present study. The Zr2Cu(Al,Ni)-type phase with high temperature stability match the result of phase equilibrium in the Zr-Cu-Ni System at 800â.

▼ For lower cost considerations, copper wire bonding has been applied in IC packaging in recent years. In this study, the intermetallics(IMCs) formed, growth and crack development were examined to evaluate the reliability of several copper wires with/ without wire surface coatings.In this study, the reliability tests include HTST, PCT, and TCT. The wire types are the 0.7 mil 4N copper wires, the Palladium coated-Copper (Pd-Cu) wires, and Au-Pd-plated copper wires. And there are three substrate types with the aluminum pad thickness of 1.6/2.8/4 micrometer. For the HTST test samples, two aging temperatures, 175âand 205â were applied and the aging periods from 150 hrs to 2000 hrs. The microstructure of micro joints are cross-sectioned and examined under an electron microprobe to verified the formed intermetallic phases for the samples tested in various aging periods. The samples under PCT and TCT tests are examined for the corrosion and crack formation behavior. The formation of IMCs, Cu9Al4, CuAl and CuAl2, which are main compounds formed in copper wire bonding micro joints. The Al-rich phase (CuAl2) has high priority, and the second phase(Cu9Al4) appear on the interface near the copper wire side. After long period aging, the Cu-rich phase(Cu9Al4) expected to form when Al pad be consumed. However, in the thicker Al pad cases, the Cu9Al4 phase will be replace by the first phase(CuAl2) finally. The results also show that, the kirkendall voids accumulate and form cracks in the bonding micro joint, and therefore make the micro joint fail. The intermetallic formation sequences of different wire types are shown for a comparison.The second part of study is about Ag wire bonding process. Ag wire has good electric conductivity, thermal conductivity, high current withstand capacity, and easy to store. However, compared to Au-Al wire bonding system, it is not enough to understand Ag-Al-Au phase diagram and the intermetallic formation of Ag-alloy wire bonding. This study of Ag wire can provide more information about diffusion paths and phase identification of Ag-Al-Au ternary system in the lower temperature.
