Abstract
In one general aspect, a power device includes an active region having a plurality of pillars of a first conductivity type alternately arranged with a plurality of pillars of a second conductivity type where the plurality of pillars of the second conductivity type in the active region each have substantially the same width. The power device includes a termination region surrounding at least a portion of the active region and having a plurality of pillars of the first conductivity type alternately arranged with a plurality of pillars of the second conductivity type where the plurality of pillars of the second conductivity type in the active region each have substantially the same width and are smaller than each width of the pillars of the second conductivity type in the termination region. The power device includes a transition region disposed between the active region and the termination region.
