Claim Text:
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, an electrostatic discharge protection structure on the first isolation layer, the electrostatic discharge protection structure having a first terminal and a second, different terminal, a second isolation layer on the electrostatic discharge protection structure, a first contact structure electrically coupled to the first terminal and a second contact structure electrically coupled to the second terminal, wherein both the first and second contact structures extend vertically through the second isolation layer, and a heat dissipation structure extending vertically through the second isolation layer and having a first end in contact with the electrostatic discharge protection structure and a second end which is in contact with an electrically isolating region, wherein the heat dissipation structure is distinct from the first and second contact structures.
