Patent ID: 8148202

Claim:
A method for fabricating an integrated circuit chip assembly module comprised of a first integrated circuit chip and a second integrated circuit chip, wherein the integrated circuit chips have an active face upon which active circuitry and signal pads reside, and a back face opposite the active face, the method comprising: fabricating a substrate of the first integrated circuit chip from a solid block of a single material, wherein the material is a substance through which electromagnetic signals can pass; fabricating a set of smart pixels in the circuitry in the active face of the first integrated circuit chip, wherein each smart pixel includes a separate circuit for performing a function of the smart pixel; and fabricating the integrated circuit chip assembly module to create an electromagnetic via that facilitates using non-conductive electromagnetic signaling for communication between the signal pads on the first integrated circuit chip and the signal pads on a second integrated circuit chip by coupling the first and second integrated circuit chips so that the substrate of the first integrated circuit chip is configured as the electromagnetic via; wherein the electromagnetic via couples the signal pads on the active face of the first integrated circuit chip to the back face of the first integrated circuit chip so that the first integrated circuit chip can communicate with the second integrated circuit chip while the back face of the first integrated circuit chip is adjacent to the active face of the second integrated circuit chip.
