A method for producing a transistor component having a field plate. One embodiment includes providing a semiconductor body having a first side, and including a first trench extending into the semiconductor body. A field plate dielectric layer is produced on the first side and at uncovered areas of the first trench such that a residual trench remains. A field plate layer is produced in the residual trench. The first side of the semiconductor body is uncovered using a polishing method. The field plate dielectric layer is partially removed from the at least one first trench proceeding from the first side.
