Abstract:
A MOS transistor having an increased gate-drain capacitance is described. One embodiment provides a drift zone of a first conduction type. At least one transistor cell has a body zone, a source zone separated from the drift zone by the body zone, and a gate electrode, which is arranged adjacent to the body zone and which is dielectrically insulated from the body zone by a gate dielectric. At least one compensation zone of the first conduction type is arranged in the drift zone. At least one feedback electrode is arranged at a distance from the body zone, which is dielectrically insulated from the drift zone by a feedback dielectric and which is electrically conductively connected to the gate electrode.
