Abstract
A semiconductor device has a substrate having a plurality of neighboring trenches, and a contact area, one mesa stripe each being formed between two neighboring trenches. The contact area contacts mesa stripes and surrounds an opening region in which the contact area is not formed and which is formed such that the contact area contacts the same mesa stripes at two positions between which the opening region is arranged, and the opening region having a region of elongate extension which intersects the mesa stripes in a skewed or perpendicular manner.
