Patent ID: 7951663

Claim:
A method of making a semiconductor device, comprising: providing a temporary substrate; forming an interface layer over the temporary substrate; forming a smooth conductive layer over the interface layer; forming a first insulating layer over a first surface of the smooth conductive layer; forming a second insulating layer over the first insulating layer and first surface of the smooth conductive layer; removing a portion of the second insulating layer to expose the first insulating layer and interface layer; forming a first conductive layer over the first insulating layer and interface layer; forming a third insulating layer over the second insulating layer and first conductive layer; removing the temporary substrate to expose the interface layer; removing a portion of the interface layer to expose the smooth conductive layer and first conductive layer; forming a second conductive layer over the first conductive layer and a second surface of the smooth conductive layer opposite the first surface of the smooth conductive layer; and forming a fourth insulating layer over the second conductive layer and interface layer.
