Abstract
A semiconductor power device includes an n-type drift layer, a plurality of first p-doped regions, a plurality of n-doped regions, a plurality of second p-doped regions, a gate dielectric layer, a gate electrode, an interlayer dielectric layer and a plurality of source contacts. Each first p-doped region includes a first p-doped portion and a plurality of first p-doped arms extending outwards from the first p-doped portion. Each n-doped region includes an n-doped portion and a plurality of n-doped arms extending outwards from the n-doped portion.
