Abstract:
A trench is formed that extends from a main surface into a crystalline silicon carbide semiconductor layer. A mask is formed that includes a mask opening exposing the trench and a rim section of the main surface around the trench. By irradiation with a particle beam a first portion of the semiconductor layer exposed by the mask opening and a second portion outside of the vertical projection of the mask opening and directly adjoining to the first portion are amorphized. A vertical extension of the amorphized second portion gradually decreases with increasing distance to the first portion. The amorphized first and second portions are removed.

Claim (Index 6):
A semiconductor device, comprising:\n a trench extending from a first surface of a semiconductor body into the semiconductor body, the semiconductor body comprising crystalline silicon carbide; wherein the trench has a chamfered and/or substantially rounded rim with a tilted surface section and a tapering surface section; and wherein the tilted surface section and the first surface enclose a first angle and the tilted surface section and the tapering surface section enclose a second angle, the first angle being different from the second angle.
