Patent ID: 8445960

Claim:
A device comprising: a substrate defined with a device region; a transistor in the device region, wherein the transistor includes a gate having first and second sides, a first diffusion region in the device region adjacent to the first side of the gate, and a second diffusion region in the device region adjacent to the second side of the gate, wherein the first and second diffusion regions comprise dopants of a first polarity type; a self-aligned body disposed in the substrate adjacent to the first side of the gate, the body comprises dopants of a second polarity type, the self-aligned body encompassing the first diffusion region, the self-aligned body having an under-lapping portion under the gate, the under-lapping portion having a length L; a drift well in the substrate having dopants of the first polarity type, the drift well encompassing at least a portion of the body and second diffusion region; a second isolation well in the substrate encompassing the drift well, the second isolation well having second polarity type dopants; and a body connector having second polarity type dopants in communication with the body and second isolation well.
