Patent ID: 7446354

Claim:
A semiconductor device, comprising: a substrate having a major surface, wherein the substrate comprises a first conductivity type; a pedestal structure formed overlying a portion of the major surface; a conductive material disposed along a side surface of the pedestal structure to form a first conduction electrode of the semiconductor device; a body region of a second conductivity type formed in the substrate adjacent the major surface and the first conduction electrode, wherein a portion of the body region forms a channel region when the semiconductor device is in operation; a current carrying region of the first conductivity type formed in the body region; a first doped region of the second conductivity type formed in the substrate in proximity to a drain edge of the channel region so that the first doped region enhances breakdown voltage of the semiconductor device when in operation, wherein the first doped region is spaced apart from the body region so that a portion of the substrate is between the body region and the first doped region in proximity to the first major surface; and a first conductive layer in contact with the first doped region.
