Abstract
An improved superjunction semiconductor device includes a charged balanced pylon in a body region, where a top of the pylon is large to create slight charge imbalance. A MOSgated structure is formed over the top of the pylon and designed to conduct current through the pylon. By increasing a dimension of the top of the pylon, the resulting device is less susceptible to variations in manufacturing tolerances to obtain a good breakdown voltage and improved device ruggedness.
