(Invited) Self-Assembly Based Multichip-to-Wafer Bonding Technologies for 3D/Hetero Integration

Abstract

We have proposed and developed 3D integration technologies based on self-assembly using surface tension of liquid in this decade. In this paper, microbump bonding and bumpless bonding in face-up and/or face-down configuration are introduced for fine-pitch interconnect formation. In addition, “non-transfer stacking”, in other word, flip-chip self-assembly and “transfer stacking” called reconfigure-wafer-to-wafer using SAE carrier are explained.
