Abstract:
A trench MOSFET device is fabricated with body source regions that undulate along a channel width direction of the MOSFET device such that the body region and source region have variations in depth along the channel width direction. The undulations increase a channel width of the MOSFET device.

Claim (Index 4):
The method of  claim 1 , wherein forming a lightly doped epitaxial layer of a first conductivity type on a heavily doped semiconductor substrate of the first conductivity type comprises:\n forming a first epitaxial layer on the semiconductor substrate; forming a buried layer using a first mask, wherein the first mask defines the third undulation; and forming a second epitaxial layer on the buried layer.
