Abstract

A semiconductor device includes a plurality of compensation regions of a first conductivity type arranged in a semiconductor substrate. The semiconductor device further includes a plurality of drift region portions of a drift region of a vertical electrical element arrangement. The drift region has a second conductivity type. The drift region portions and the compensation regions are arranged alternatingly. At least portions of a border of a depletion region occurring in a static blocking state of the vertical electrical element arrangement are located within the drift region portions at a depth of less than a depth of at least a subset of the compensation regions.
