Abstract
A semiconductor component is disclosed herein comprising a drift zone and a drift control zone. The drift control zone is arranged adjacent to the drift zone and is dielectrically insulated from the drift zone by a dielectric layer. The drift control zone includes at least one first semiconductor layer and one second semiconductor layer. The first semiconductor layer has a higher charge carrier mobility than the second semiconductor layer.
