Abstract:
A semiconductor device fabrication method includes forming first and second spaced apart base regions and source regions in a substrate with a portion of a drift region therebetween. The method further includes forming at least a first trench extending laterally through the base region, the drift region and the source region, the first trench extending vertically partially through the source region. The method also includes forming a first oxide layer over the trenched upper surface, and forming a polysilicon layer over the first oxide layer. The polysilicon layer is patterned to form the gate conductor, and a drain contact is formed on a bottom surface of the semiconductor substrate.

Claim (Index 13):
The method of  claim 9 , wherein step d) further comprises forming the first trench using reactive ion etching to remove portions of at least the first and second source strips and the first and second base strips.
