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 12):
The method of  claim 1 , wherein forming a source region of the first conductivity type provided in top portions of the body region comprises:\n forming the body region using a third mask, wherein the third mask has an opening to define the first undulation; and implanting dopants of the first conductivity type into the body region to form the source region, wherein the dopants of the first conductivity are implanted deeper into the body region under the opening to form the second undulation.
