Abstract:
1. A device comprising: a first integrated circuit (IC) die that includes a first coil proximate to a first surface of the first IC die, and a plurality of first bond pads, wherein the plurality of first bond pads are electrically coupled to the first coil; an inductive coupling substrate that includes a second coil and a first signal communication interface, wherein the second coil is proximate to a first surface of the inductive coupling substrate, and the second coil is electrically coupled to the first signal communication interface; a second IC die that includes a second signal communication interface and a plurality of second bond pads, wherein the second signal communication interface is electrically coupled to the plurality of second bond pads, and wherein the first IC die, the second IC die, and the inductive coupling substrate are arranged within the device so that the first surface of the inductive coupling substrate faces the first surface of the first IC die and a first surface of the second IC die, the first coil and the second coil are aligned with each other across a gap between the first IC die and the inductive coupling substrate, the first IC die and the inductive coupling substrate are galvanically isolated from each other, and the first signal communication interface and the second signal communication interface are communicably coupled; and one or more dielectric components within the gap, which are positioned directly between the first coil and the second coil.
