Abstract
A semiconductor device includes a first ridge and a second ridge extending from a first main surface of a semiconductor substrate, the first and second ridges running in a first direction. A body region is disposed in a portion of the semiconductor substrate between the first ridge and the second ridge, the first and second ridges being connected with the body region. A plurality of further ridges are formed in the body region, the further ridges extending in a second direction intersecting the first direction. A gate electrode is adjacent to the body region, the gate electrode running in the first direction and being disposed at at least two sides of the further ridges.
