Abstract:
A semiconductor device includes a trench structure extending into a semiconductor body from a first surface. The trench structure has a shield electrode, a dielectric structure and a diode structure. The diode structure is arranged at least partly between the first surface and a first part of the dielectric structure. The shield electrode is arranged between the first part of the dielectric structure and a bottom of the trench structure. The shield electrode and the semiconductor body are electrically isolated by the dielectric structure. Corresponding methods of manufacture are also described.

Claim (Index 21):
The method of  claim 20 , further comprising:\n simultaneously forming the trench structure and a gate trench structure extending into the semiconductor body from the first surface; applying polycrystalline silicon on the first surface of the semiconductor body to fill the trench structure and the gate trench structure; removing the polycrystalline silicon to a predetermined trench depth to form the shield electrode in the trench structure and the gate trench structure; forming the first part of the dielectric structure on the shield electrode in the trench structure and the gate trench structure; applying polycrystalline silicon on the first part of the dielectric structure to fill the trench structure and the gate trench structure; and carrying out a chemical mechanical polishing process or a plasma etching process to remove the polycrystalline silicon from above the trench structure and the gate trench structure, such that the polycrystalline silicon in the gate trench structure and the polycrystalline silicon in the trench structure are separated from one another.
