A power transistor includes a semiconductor layer an electrode layer. The semiconductor layer having a source zone, a drain zone spaced apart from the source zone in a lateral direction, a drift zone adjacent to the drain zone, and a body zone. The body zone is interposed between the drift zone and the source zone. The electrode layer is dielectrically insulated from the semiconductor layer, and includes a gate electrode divided into at least two sections and a field plate. The field plate is arranged at a first height level relative to the semiconductor layer. A first gate electrode section is arranged at least partially at a second height level, which is lower than the first height level relative to the semiconductor layer. A second gate electrode section, which is laterally displaced from the first gate electrode section, is disposed at a first intermediate level arranged between the first and second height levels. |
