摘要:
A semiconductor component includes a semiconductor body and a second semiconductor zone of a first conductivity type that serves as a rear side emitter. The second semiconductor zone is preceded by a plurality of third semiconductor zones of a second conductivity type that is opposite to the first conductivity type. The third semiconductor zones are spaced apart from one another in a lateral direction. In addition, provided within the semiconductor body is a field stop zone spaced apart from the second semiconductor zone, thereby reducing an electric field in the direction toward the second semiconductor zone.
