Abstract
Low resistance contacts for establishing an electrical pathway to an integrated surface substrate are provided. The pathway is formed by the connection of a p+ doped channel stop region with a p+ doped extrinsic layer. P+ doped polysilicon contacts are positioned on the substrate surface. In one embodiment, a metal silicide layer connects the polysilicon contacts and overlies the p+ doped extrinsic layer.
