Abstract
Transistor configurations have trench transistor cells disposed along trenches in a semiconductor substrate with two or more electrode structures disposed in the trenches, and also metallizations are disposed above a substrate surface of the semiconductor substrate. The trenches extend into an inactive edge region of the transistor configuration and an electrically conductive connection between the electrode structures and corresponding metallizations are provided in the edge region.
