Abstract:
A semiconductor device and method is disclosed. In one example, the method for forming a semiconductor device includes forming a trench extending from a front side surface of a semiconductor substrate into the semiconductor substrate. The method includes forming of material to be structured inside the trench. Material to be structured is irradiated with a tilted reactive ion beam at a non-orthogonal angle with respect to the front side surface such that an undesired portion of the material to be structured is removed due to the irradiation with the tilted reactive ion beam while an irradiation of another portion of the material to be structured is masked by an edge of the trench.

Claim (Index 12):
The semiconductor device of  claim 7 , wherein a side wall of the gate trench is covered by an insulating layer with vertically varying thickness.
