Abstract:
1. A MOS transistor comprising: a drift zone of a first conduction type; at least one transistor cell having a body zone, a source zone separated from the drift zone by the body zone, and a gate electrode, arranged adjacent to the body zone and dielectrically insulated from the body zone by a gate dielectric; at least one compensation zone of a second conduction type arranged in the drift zone; and at least one feedback electrode arranged at a distance from the body zone, dielectrically insulated from the drift zone by a feedback dielectric and electrically conductively connected to the gate electrode, wherein the compensation zone has a first compensation zone section and a second compensation zone section, wherein the first compensation zone section is doped more highly than the second compensation zone section and is arranged nearer to the feedback electrode than the second compensation zone section.
