Patent ID: 7525199

Claim:
A computer system, comprising: a substrate; a first integrated circuit (IC) having an inactive side disposed facing the substrate; a second IC having an active side disposed facing the substrate, wherein a corner of the second IC overlapping with a first corner of the first IC is used to transfer data between the first IC and the second IC by proximity communication, and wherein the second IC is larger than the first IC; a third IC having an active side disposed facing the substrate, wherein a corner of the third IC overlapping with a second corner of the first IC is used to transfer data between the first IC and the third IC by proximity communication, and wherein the third IC is larger than the first IC; a fourth IC having an active side disposed facing the substrate, wherein a corner of the fourth IC overlapping with a third corner of the first IC is used to transfer data between the first IC and the forth IC by proximity communication, and wherein the fourth IC is larger than the first IC; and a fifth IC having an active side disposed facing the substrate, wherein a corner of the fifth IC overlapping with a fourth corner of the first IC is used to transfer data between the first IC and the fifth IC by proximity communication, and wherein the fifth IC is larger than the first integrated circuit.
