Original Abstract Submitted
A vertical power transistor having front and rear sides. The vertical power transistor includes a drift region that includes a first doping with a first charge carrier type, and a body region that includes a second doping with a second charge carrier type. The body region is situated on the drift region, and includes trenches that extend, starting from the front side, essentially perpendicularly into the drift region. First and second areas are situated between the trenches. The first areas are situated centrally between the trenches, and the second areas are situated between the first areas and the trenches. The first and second areas, starting from the body region, extend essentially perpendicularly into the drift region. The first areas include a third doping with the second charge carrier type, and the second areas include the first doping with the first charge carrier type.
