A semiconductor device is disclosed. One embodiment includes a trench within a semiconductor body and a gate insulating structure at opposing sidewalls within the trench. A gate electrode structure adjoins the gate insulating structure within the trench and a dielectric structure adjoins the gate electrode structure within the trench. The gate electrode structure is in contact with the semiconductor body at a bottom side of the trench and is electrically coupled to a drain zone over an element having a voltage blocking capability.
