Patent ID: 8093676

Claim:
A semiconductor component comprising: a semiconductor body having a first side, a second side, an edge delimiting the semiconductor body in a lateral direction, and also having an inner region and an edge region arranged between the inner region and the edge in the lateral direction; a first semiconductor zone of a first conduction type, which is arranged in the inner region and in the edge region; a second semiconductor zone of a second conduction type complementary to the first conduction type, which is arranged in the inner region and which is adjacent to the first semiconductor zone in a direction of the first side; a trench arranged in the edge region and having first and second sidewalls and a bottom, which extends into the semiconductor body proceeding from the first side; a doped first sidewall zone of the second conduction type, which is adjacent to the first sidewall of the trench, a doped second sidewall zone of the second conduction type, which is adjacent to the second sidewall of the trench, and a doped bottom zone of the second conduction type, which is adjacent to the bottom of the trench, and which is arranged within the first semiconductor zone, wherein doping concentrations of the sidewall zones are lower than a doping concentration of the bottom zone and the doped first sidewall zone and the doped second sidewall zone are on opposite sides of the trench; and a third semiconductor zone of the first conduction type, adjacent to the first semiconductor zone in the edge region in a direction of the first side, doped more highly than the first semiconductor zone and extending in the lateral direction from the trench or the second sidewall zone as far as the edge.
