Abstract

A semiconductor device and method of forming the same is described. In an example, a polysilicon layer is deposited on a substrate having at least one polysilicon ring. The substrate is doped using the polysilicon layer as a mask to form doped regions in the substrate. A dielectric layer is deposited over the polysilicon layer and the substrate. The dielectric layer is etched to expose portions of the polysilicon layer. A metal layer is deposited on the dielectric layer. The metal layer, the dielectric layer, and the exposed portions of the polysilicon layer are etched such that at least a portion of each polysilicon ring is removed.
