Abstract

The specification describes Schottky barrier devices with distributed guard rings. In one embodiment the guard ring only partially overlaps the barrier. In another embodiment the guard ring is spaced from the barrier throughout, but separated by an MOS gate so that the guard ring and barrier are connected at low bias by an inversion layer.
