Abstract:
A semiconductor device includes a semiconductor body having a first surface and a second surface opposite to the first surface. A transistor structure is formed is the semiconductor body. A trench structure extends from the first surface into the semiconductor body. An electrostatic discharge protection structure is accommodated in the trench structure. The electrostatic discharge protection structure includes a first terminal region and a second terminal region. A source contact structure at the first surface is electrically connected to source regions of the transistor structure and to the first terminal region. A gate contact structure at the first surface is electrically connected to a gate electrode of the transistor structure and to the second terminal region.

Claim (Index 19):
The method of  claim 17 , wherein forming the transistor structure and forming the trench structure comprises:\n simultaneously forming a gate trench and the trench structure extending from the first surface into the silicon carbide semiconductor body; applying polycrystalline silicon on the surface of the silicon carbide semiconductor body until the trench structure and the gate trench are filled; and carrying out a chemical mechanical polishing process to remove polycrystalline silicon present above the trench structure and the gate trench, such that the polycrystalline silicon in the gate trench and the polycrystalline silicon in the trench structure are separated from one another.
