Abstract
A charge-compensation semiconductor device includes a semiconductor body having a first surface, a lateral edge delimiting the semiconductor body in a horizontal direction substantially parallel to the first surface, an active area, a peripheral area arranged between the active area and the lateral edge, a drift region, first compensation regions forming respective first pn-junctions with the drift region, and second compensation regions extending from the first surface into the drift region and forming respective second pn-junctions with the drift region. The first compensation regions form in the active area a lattice comprising a first base vector having a first length. The second compensation regions have, in a horizontal direction parallel to the first surface, a horizontal width which decreases with an increasing vertical distance from the first surface and with a decreasing horizontal distance from the edge.
