Patent ID: 8338294

Claim:
A method of forming a semiconductor device, comprising: providing a substrate, the substrate comprising a layer of semiconductor material on a layer of electrically insulating material; forming a first metallization layer comprising a plurality of electrically conductive features on the substrate over a first side of the layer of semiconductor material opposite the layer of electrically insulating material; forming a plurality of through wafer interconnects at least partially through the substrate, and forming at least one through wafer interconnect of the plurality of through wafer interconnects to extend through each of the first metallization layer and the layer of semiconductor material; forming a second metallization layer comprising a plurality of electrically conductive features over a second side of the layer of semiconductor material opposite the first side of the layer of semiconductor material; and providing an electrical pathway extending continuously through the first metallization layer, the substrate, and the second metallization layer between a first processed semiconductor structure carried by the substrate on the first side of the layer of semiconductor material and a second processed semiconductor structure carried by the substrate on the first side of the layer of semiconductor material.
