Abstract
One embodiment of the present invention provides an integrated circuit chip, including an active face upon which active circuitry and signal pads reside, and a back face opposite the active face. The integrated circuit chip additionally comprises an electromagnetic via that facilitates communication between signal pads on the integrated circuit chip and signal pads on a second integrated circuit chip. The electromagnetic via couples a signal pad on the active face of the integrated circuit chip to the back face of the integrated circuit chip so that the integrated circuit chip can communicate with the second integrated circuit chip while the back face of the integrated circuit chip is adjacent to the active face of the second integrated circuit chip. Moreover, the electromagnetic via operates by facilitating non-conductive signaling through the integrated circuit chip.
