Abstract
An IC structure includes a substrate region having a first doping type and including an upper surface, first and second regions within the substrate region, each of the first and second regions having a second doping type opposite the first doping type, and a gate conductor including a plurality of conductive protrusions extending into the substrate region in a direction perpendicular to a plane of the upper surface. The conductive protrusions are electrically connected to each other, and at least a portion of each conductive protrusion is positioned between the first and second regions.
