An integrated circuit device includes first and second arrays of semiconductor dice. Each array of dice is arranged in face-to-face relation to the other array of dice, thus forming a lower layer of dice and an upper layer of dice. The layers are aligned so that each upper layer die straddles two or more of the lower layer dice, thus defining overlap regions. In the overlap regions, signal pads of one layer are aligned with corresponding signal pads of the other layer. The two layers are spaced apart, thus creating a capacitance-based communication path between the upper and lower layers via the signal paths.
