Abstract
A semiconductor device includes a semiconductor substrate defining a major surface. The device further includes a first region including at least a first pillar of a first conductivity type extending in a vertical orientation with respect to the major surface. The device further includes a second region of the first conductivity type. The first pillar includes a higher doping concentration than the second region. The device further includes a Schottky contact coupled to the second region.
