Patent ID: 7106079

Claim:
A method for improving communication between capacitively coupled integrated circuit chips, comprising: placing a first integrated circuit chip near a second integrated circuit chip, wherein the first integrated circuit chip and the second integrated circuit chip communicate with each other through capacitive coupling; situating an interposer over capacitive communication pads on the first integrated circuit chip, wherein the interposer is composed of an anisotropic material; providing a plurality of alignment spurs on the first integrated circuit chip and the second integrated circuit chip to align the first integrated circuit chip and the second integrated circuit chip; and situating the second integrated circuit chip so that communication pads on the second integrated circuit chip are aligned to capacitively couple signals between the first integrated circuit chip and the second integrated circuit chip through the interposer; whereby increased dielectric permittivity of the interposer can improve capacitive coupling between opposing communication pads on the first integrated circuit chip and the second integrated circuit chip, and whereby increased dielectric permittivity of the interposer can reduce cross talk between communication pads on the first integrated circuit chip and pads adjacent to the opposing communication pads on the second integrated circuit chip.
