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 7):
A semiconductor device comprising:\n a gate trench of a vertical transistor structure, wherein the gate trench extends from a front side surface of a semiconductor substrate into the semiconductor substrate; and a gate electrode located within the gate trench, wherein the gate electrode comprises a slanted or triangular top; wherein at least one lateral part of an edge surface of the gate trench comprises at least one of a minimal angle between adjacent surface portions of the at least one lateral part of the edge surface larger than 100\u00b0 and a minimal radius of curvature of the at least one lateral part of the edge surface larger than 100 nm; and wherein the at least one lateral part of the edge surface extends from the front side surface of the semiconductor substrate to a side wall of the trench.
