Zusammenfassung:A vertical SiC MOSFET having a source terminal, a drain terminal, and a gate region, as well as an epitaxial layer disposed between the source terminal and the drain terminal and having a doping of a first type, is furnished, a horizontally extending intermediate layer, which has regions having a doping of a second type different from the doping of a first type, being embedded into the epitaxial layer. The vertical SiC MOSFET is notable for the fact that at least the regions having doping of a second type are electrically conductively connected to the source terminal. The gate region can be disposed in a gate trench.
