Vertikales Halbleiterbauelement mit reduziertem elektrischem Oberflächenfeld

摘要

A vertical semiconductor component having a semiconductor body of a first conductivity type is described. In a surface region of the semiconductor body, at least one zone of a second conductivity type, opposite to the first conductivity type, is embedded. Regions of the second conductivity type are provided in the semiconductor body in a plane running substantially parallel to the surface of the surface region. The regions are in this case sufficiently highly doped that they cannot be depleted of charge carriers when a voltage is applied.
