Abstract

A semiconductor component includes: gate structures extending from a first surface into an SiC semiconductor body; a drift zone of a first conductivity type formed in the SiC semiconductor body; first mesas and second mesas arranged between the gate structures in the SiC semiconductor body; body areas of a second conductivity type arranged in the first mesas and the second mesas, the body areas each adjoining a first side wall of one of the gate structures; first shielding areas of the second conductivity type adjoining a second side wall of one of the gate structures; second shielding areas of the second conductivity type adjoining the body areas in the second mesas; and diode areas of the conductivity type of the drift zone, the diode areas forming Schottky contacts with a load electrode between the first shielding areas and the second shielding areas.
