Abstract
In one general aspect, a termination structure can include a plurality of pillars of a first conductivity type formed inside a termination region of a second conductivity type opposite the first conductivity type where the plurality of pillars define a plurality of concentric rings surrounding an active area of a semiconductor device. The termination structure can include a conductive field plate where the plurality of pillars includes a first pillar coupled to the conductive field plate. The termination structure can include a dielectric layer where the plurality of pillars include a second pillar insulated by the dielectric layer from a portion of the conductive field plate disposed directly above the second pillar included in the plurality of pillars.
