Abstract
A method for producing Schottky diodes having a protective ring in an edge region of a Schottky contact. The protective ring is produced by a protective ring material that is deposited onto a surface of a semiconductor layer, which surface is provided with a patterned masking layer beforehand, and the protective ring material subsequently being siliconized. In this case, the protective ring material constitutes a metal, in particular a high barrier metal, which has, in particular, platinum.
