Abstract:
1. A semiconductor component, comprising: a semiconductor body having a semiconductor substrate and a doped semiconductor layer provided on the semiconductor substrate, the semiconductor substrate having a first terminal zone of a first conduction type and the doped semiconductor layer having a second terminal zone of the first conduction type, a channel zone of a second conduction type short circuited with the second terminal zone, a drift zone of the first conduction type having a doping which is weaker than those of the terminal zones, the drift zone being disposed between the channel zone and the first terminal zone, and the channel zone being disposed between the drift zone and the second terminal zone, a control electrode insulated from the channel zone for controlling a conduction channel in the channel zone between the second terminal zone and the drift zone, a compensation structure for charge compensation, the compensation structure comprising a compensation zone between the drift zone and the channel zone, and a field stop zone of the first conduction type disposed between the first terminal zone and the drift zone, the field stop zone having heavier doping than the drift zone and a weaker doping than the first terminal zone, a maximum doping concentration of the field stop zone being at most a factor of about 10
