Chip-To-Chip Interconnection by Mechanical Caulking Using Reflowed Sn Bumps

A new chip-to-chip interconnection method utilizing mechanical caulking has been developed recently. In this method, bonding between the chips is achieved by deformation-injection of Au stud bump on a chip into the through via hole in the other chip. In this paper, we introduce a modified caulking technology using reflowed Sn bumps instead Au stud bumps sinc e Sn can be deformed more easily than Au. The chip-to-chip interconnection using reflowed Sn bumps and through via hole electrodes was successfully made at room temperature or at 270 ℃. The contact resistance of the solder joint was less than 35 mΩ per joint.
