  • Patent number: 9865677
    Abstract: 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.
