Claim:
1. A super-junction semiconductor device, comprising: a junction termination area at a first surface of a semiconductor body and at least partly surrounding an active cell area, wherein an inner part of the junction termination area is arranged between an outer part of the junction termination area and the active cell area; a charge compensation device structure comprising first regions of a first conductivity type and second regions of a second conductivity type disposed alternately along a first lateral direction, first surface areas corresponding to a projection of the first regions onto the first surface, and second surface areas corresponding to a projection of the second regions onto the first surface; and at least one of a first junction termination extension structure and a second junction termination extension structure, wherein first dopants of the first conductivity type constitute the first junction termination extension structure, wherein, in the outer part of the junction termination area, a projection area of the first junction termination extension structure onto the first surface is at least partly included in the second surface areas and is at least partly excluded from the first surface areas, and second dopants of the second conductivity type constitute the second junction termination extension structure, wherein, in the inner part of the junction termination area, a projection area of the second junction termination extension structure onto the first surface is at least partly included in the first surface areas and is at least partly excluded from the second surface areas.
