Broadly, the main objective of my research is to explore, identify, develop, refine, and verify enabling technology for three-dimensional (3-D) integration and packaging of integrated circuits on mature silicon platform in order to maintain performance growth (3-5 years target) as well as to offer functional diversification in future integrated circuits and systems (>5 years target). This objective is aligned with the “More Moore” and “More than Moore” activities in the semiconductor industry. Specifically, the end goals are three-fold:
1) To invent and develop advanced micro-fabrication technology that are scalable and reliable, such as fine pitch metal bonding and through silicon via, to enable 3-D stacking and interconnection of ultra-thin integrated circuits on a silicon platform;
2) To utilize the third (i.e. vertical) dimension of integrated circuits for direct placement of IC and non-IC blocks for performance enhancement as well as functional diversification in future micro-systems;
3) To formulate and develop a “pick, place, and mix” method that enables large area direct sorting, precision placement, and mixing of various layers on silicon platform to realize true heterogeneous integration of materials, devices, and functions.
In addition to 3D integration and packaging at the interconnect and package levels, I am also actively engaged in monolithic group-IV hetero-structures at the material and substrate levels including epitaxial growth, bonding, transfer, processing, and devices.
Current projects are:
(1) 3D IC packaging and integration - Fine-pitch and high through-put Cu-Cu bonding, through silicon via (TSV), TSV-less CMOS-MEMS stacking;
(2) InP/Si bonding - Surface treatment, precision bonding, thermal characteristics;
(3) Advanced substrate - Ge/Si, GOI, III-V/Ge/Si;
(4) Thermal management of integrated electronics - vapor chamber design, modeling, fabrication and characterization.
