Abstract
One embodiment of the present invention provides a system that facilitates capacitive communication between integrated circuit chips. The system includes a substrate having an active face upon which active circuitry and signal pads reside, and a back face opposite the active face. The system additionally includes an integrated circuit chip having an active face upon which active circuitry and signal pads reside, and a back face opposite the active face. Additionally, the integrated circuit chip is pressed against the substrate such that the active face of the integrated circuit chip is parallel to and adjacent to the active face of the substrate, and capacitive signal pads on the active face of the integrated circuit chip overlap signal pads on the active face of the substrate. The arrangement of the substrate and integrated circuit chip facilitates communication between the integrated circuit chip and the substrate through capacitive coupling via the overlapping signal pads.
