Abstract

The arrangement with a pn-junction and the measure for reducing the risk of a breakdown of the junction is composed of a combination of a field plate (4) and a stop electrode respectively having a multi-step edge section (40 or, respectively, 50) with a JTE technique, as a result whereof blocking voltages clearly above 2500 Volts can be achieved given slight space requirement.
