Abstract:
1. An integrated circuit, comprising: a silicon-based region extending from a first peripheral edge to a second peripheral edge, said second peripheral edge coincident with an edge of a laterally adjacent insulating material, wherein a surface of said silicon-based region includes a cavity which laterally extends out to an edge that is also coincident with said second peripheral edge of the silicon-based region; a insulating layer overlying the silicon-based region, the insulating layer including an opening therein aligned with the cavity on the surface of the silicon-based region; and a metallic material that at least partially fills both the opening in the insulating layer and the cavity on the surface of the silicon-based region so as to form a contact pad with that silicon-based region which laterally extends out to said second peripheral edge of the silicon-based region.
