Patent ID: 8853779

Claim:
A transistor, comprising: a first semiconductor layer of a first conductivity, at least a portion of the first semiconductor layer including a drain region; a first trench disposed in the first semiconductor layer; a first filler of a second conductivity disposed in the first trench; a first body region of the second conductivity comprising first lateral extensions that extend laterally away from the first trench along a non-planar surface; a first deep-body implant region having a high doping of the second conductivity disposed at least within the first lateral extensions of the first body region; a first source region of the first conductivity in contact with the first body region; a second trench disposed in the first semiconductor layer adjacent the first trench; a second filler of the second conductivity disposed in the second trench; a second body region of the second conductivity comprising second lateral extensions that extend laterally away from the second trench along a non-planar surface; a second source region of the first conductivity in contact with the second body region; wherein the first deep-body implant region extends through the first body region to a top of the first filler in the first trench.
