Abstract of the Disclosure

This application discloses guardring structures adapted for use with Schottky barrier devices to decrease the leakage current and increase the reverse breakdown voltage. In particular, Schottky barrier devices, including diodes and particle detectors, are provided with p-n junction and metal-insulator-semiconductor (MIS) guardrings. In addition, a Schottky barrier device having a closure guardring is also disclosed.
