Claim:
1. A semiconductor device, comprising: a semiconductor body having a first surface and a second surface opposite to the first surface, a first isolation layer on the first surface of the semiconductor body, a first electrostatic discharge protection structure on the first isolation layer, the first electrostatic discharge protection structure having a first terminal and a second terminal, a second isolation layer on the first electrostatic discharge protection structure, a gate contact pad on the second isolation layer, the gate contact pad being electrically coupled to the first terminal of the first electrostatic discharge protection structure, an electric contact structure arranged in an overlap area between the gate contact pad and the semiconductor body, the electric contact structure being electrically coupled to the second terminal of the first electrostatic discharge protection structure and electrically isolated from the gate contact pad, and a source contact pad on the second isolation layer, the source contact pad being electrically coupled to the electric contact structure; wherein the gate contact pad and the source contact pad are separate parts of a same patterned metal wiring layer within a same wiring level, and wherein a drain region of the semiconductor device is disposed at the second surface of the semiconductor body.
