Patent ID: 8247869

Claim:
A transistor comprising: a source region of a first conductivity type, the source region located in a substrate structure; a drain region of the first conductivity type, the drain region located in the substrate structure; a well region of a second conductivity type, the second conductivity type being an opposite conductivity type of the first conductivity type, the well region including a channel region of the transistor; an isolation region of a dielectric material located in the substrate structure; a drift region of the first conductivity type, the drift region including a first portion located under the isolation region and a second portion located laterally adjacent to the isolation region; wherein at a plane at a first cross-section of the transistor, the plane generally parallel to a first major surface of the substrate structure, a second portion of the drift region is located between the isolation region and the well region; a first gate structure located over the channel region; and a second gate structure located over the isolation region, wherein at the first cross section of the transistor, a first gate structure is separated from the second gate structure by a first separation space, wherein at the first cross section, the first separation space is located over a portion of the second portion of the drift region and a portion of the isolation region; wherein the first gate structure and the second gate structure are part of a contiguous structure of conductive gate material.
