Abstract
A semiconductor device includes a semiconductor body having first and second opposing surfaces in a vertical direction, and transistor cells at least partly integrated in the semiconductor body. Each transistor cell includes first and second source regions, first and second body regions, a drift region separated from the respective source region by the corresponding body region, a first gate electrode, and a control electrode. The drift region is arranged between the first and the second body region in a horizontal direction that is perpendicular to the vertical direction and extends from the first surface into the semiconductor body in the vertical direction. The first gate electrode is configured to provide a control signal for switching the transistor cell. The control electrode is configured to provide a control signal for controlling a JFET formed by the first body region, the drift region, and the second body region.
