Patent ID: 7969015

Claim:
A system for coupling a first chip to a second chip, the system comprising: a first chip including: a post comprising a first metallic material; and a malleable electrically-conductive material on the post; and a second chip, prior to its connection with the first chip, wherein the second chip includes: a recessed wall extending from an outer surface of the second chip to a location within the second chip and defining a well within the second chip; and a conductive diffusion layer material on a surface of the recessed wall within the well; wherein the post and malleable electrically-conductive material of the first chip are configured for insertion into the well; and wherein the malleable electrically-conductive material has a size that is larger than an opening of the well prior to insertion into the well and is configured to deform upon insertion into the well and form an electrically-conductive connection with the conductive diffusion layer material to create an electrically-conductive path between the first chip and the second chip.
