演講摘要

As power delivery and bandwidth demands continue to scale with Si and system scaling, packaging technology development that enables this scaling will be critical. Packaging technology is transitioning toward the three-dimensional integrated circuit (3D IC) and a larger temperature gradient is expected to be established when dissipating the heat from the surface. Hence, understanding how the temperature gradient affects diffusion behavior of 3D IC microbumps is important. In addition, when the size of the microbumps shrinks into few micrometers, the effect of electromigration and grain size cannot be ignored. In this talk, the reliability challenging- failure induced by electromigration and thermomigration of Pb-free microbump in 3D IC would be discussed. The effect of grain orientation of microbump and the reliability issue induced by fast intermetallic compound formation would be included.
