Abstract (en)

[origin: WO9962113A2] The invention relates to a method for producing Schottky diodes which comprise a guard ring (10) in the marginal area of the Schottky contact. Said guard ring (10) is produced by depositing a guard ring material (4) on the surface (8) of the semiconductor layer (2), said surface being provided with a structured masking layer (3) beforehand, and afterwards by siliconizing the guard ring material (4). The guard ring material (4) is a metal, especially a high barrier metal which, in particular, contains platinum.
