Patent ID: 6861678

Claim:
An electronic device, comprising a. a substrate, having a top surface and a bottom surface; b. a buried layer near the top surface, doped with dopant of a first polarity, electrically communicable to a drain terminal; c. a body region, having a second top surface, a second bottom surface and a second side surface; d. a portion of the body region, having doped with dopant of a second polarity, contacting a gate region communicable to a gate terminal; e. a substantially uniformly doped channel region in the body region, having a third top surface, a third bottom surface, and a third side surface communicable to the portion of the body region in d., the third bottom surface being substantially coplanar to the second bottom surfaces and contacting the buried layer, the third top surface being substantially coplanar to the second top surface and contacting a source region; and f. the source region, projecting upward from the channel region, electrically communicable to a source terminal.
