Provided is a super junction semiconductor device. The super junction semiconductor device includes a vertical pillar region located in an active region and horizontal pillar regions located in a termination region that are connected with each other while simultaneously not floating the entire pillar region in the termination region. Thus, a charge compensation difference, generated among pillar regions, is caused to be offset, although the length of the termination region is relatively short.

Super junction semiconductor device

There is provided a super junction semiconductor device. The super junction semiconductor device includes a cell area and a junction termination area disposed on a substrate, and a transition area disposed between the cell area and the junction termination area, and the cell area, the junction termination area, and the transition area each include one or more unit cells comprising a N-type pillar region and a P-type pillar region among a plurality of N-type pillar regions and a P-type pillar regions that are alternated between the cell area and the junction termination area.
