Abstract:
A method of forming a semiconductor device includes forming a source trench extending into a semiconductor body from a first surface of the semiconductor body, forming a source trench dielectric and a source trench electrode in the source trench, forming a gate trench dielectric and a gate trench electrode in a gate trench extending into the semiconductor body from the first surface, forming a body region of a first conductivity type between the gate and source trenches, forming a source region of a second conductivity type different from the first conductivity type between the gate and source trenches, forming an interconnection electrically coupling the body region and the source trench electrode, wherein the interconnection adjoins a lateral face of the source trench electrode of the body region, and forming a source contact on the source trench electrode at the first surface.

Claim (Index 12):
The method of  claim 11 , wherein the source trench and the source trench dielectric are formed such that an interface between the source trench dielectric and the semiconductor body at a sidewall of the source trench is step shaped at a transition between lower and upper parts of the source trench dielectric, and wherein the step shaped interface between the source trench dielectric and the semiconductor body directly contacts the source trench dielectric and the semiconductor body.
