Abstract

A method for producing a Schottky diode formed of a doped guard ring in an edge area of the Schottky contact is described. The guard ring is produced by depositing a high barrier material, especially made of platinum, on the surface of the semiconductor layer. The surface is provided with a structured masking layer beforehand, and which is subsequently etch-backing.
