Patent ID: 8097954

Claim:
A semiconductor device, comprising: a supporting substrate; a first semiconductor chip disposed over the supporting substrate via a first adhesive layer, the first semiconductor chip being bonded to the supporting substrate by the first adhesive layer; a second semiconductor chip or dummy chip disposed over the first semiconductor chip via a second adhesive layer, the first semiconductor chip and the second semiconductor chip or dummy chip being bonded to each other by the second adhesive layer; and a capacitor formed between the first semiconductor chip and the second semiconductor chip or dummy chip, the capacitor including the second adhesive layer used as a dielectric material, a first conductor layer formed on a surface of the first semiconductor chip as one of two mutually opposed electrodes, and a second conductor layer formed on a surface of the second semiconductor chip or dummy chip as the other of the two mutually opposed electrodes, wherein the second adhesive layer is disposed between the first and second conductor layers of the capacitor, each of the second conductor layer and the second adhesive layer has an area which is substantially equal to an area of the second semiconductor chip or dummy chip, and the second adhesive layer fully fills a gap between the first and second conductor layers throughout the area of the second semiconductor chip or dummy chip.
