Patent ID: 8901641

Claim:
A semiconductor device with a super-junction structure, comprising: a semiconductor substrate having a first conductivity type; an epitaxial layer having the first conductivity type formed over the semiconductor substrate; a first doping region having the first conductive type formed in a portion of the epitaxial layer; a second doping region having a second conductivity type formed in a portion of the epitaxial layer; a third doping region having the second conductivity type formed in a portion of the epitaxial layer, wherein the third doping region partially comprises doped polysilicon materials having the second conductivity type, and the first doping region and the third doping region are disposed at opposing sides of the second doping region, and the second doping region directly contacts the first doping region and the third doping region; a gate dielectric layer formed over the epitaxial layer, overlying the first doping region; a gate electrode formed over a portion of the gate dielectric layer; and a dielectric layer formed over the epitaxial layer; and a conductive layer formed in a portion of the dielectric layer, directly contacting the second doping region and the third doping region.
