A Schottky diode includes a metal layer (62) on an epitaxial region (24). The metal layer (62) is covered with a dielectric layer (64). An area (90) on the metal is exposed by opening a via (68) in the dielectric. The exposed area (90) is spaced from a buried perimeter (92) of the metal layer (62).
