Abstract
The invention relates to a high-voltage semiconductor component comprising semiconductor areas ( ) of alternating, different conductivity types which are arranged in a semiconductor body in an alternating manner. In the semiconductor body said semiconductor areas extend from at least one first zone ( ) to near a second zone ( ) and are variably doped so that the electric field increases progressively from one zone to the other ( )
