Abstract:
A method for fabricating a LDMOS device, including: forming a semiconductor substrate; forming a dielectric layer atop the semiconductor substrate and an electric conducting layer on the dielectric layer; forming a first photoresist layer on the electric conducting layer; patterning the first photoresist layer through a first mask to form a first opening; etching the electric conducting layer through the first opening; implanting dopants of a first doping type into the semiconductor substrate through the first opening to form a first body region adjacent to the surface of the semiconductor substrate, and a second body region located beneath the first body region; removing the first photoresist layer; etching the electric conducting layer using a second photoresist layer and a second mask.

Claim (Index 1):
An LDMOS device fabricated in a semiconductor substrate, comprising:\n a gate oxide region formed atop the semiconductor substrate; a gate polysilicon region formed on the gate oxide region; a first body region of a first doping type formed in the semiconductor substrate, wherein the first body region is located at a first side of the gate polysilicon region and adjacent to the surface of the semiconductor substrate; a second body region of the first doping type formed beneath the first body region; a source region of a second doping type formed in the first body region; a drain region of the second doping type formed in the semiconductor substrate and at a second side of the gate polysilicon region; wherein the gate polysilicon region, the first body region and the second body region are defined by the same mask and are self-aligned.
