Abstract:
A semiconductor device includes a MOS transistor located within a semiconductor substrate of a first conductivity type. The transistor includes a body well located between a drain well and a substrate contact well. A buried voltage blocking region of a second conductivity type is located within the substrate and is connected to the body well. The buried voltage blocking region extends toward the substrate contact well, with an unmodified portion of the substrate remaining between the voltage blocking region and the substrate contact well.

Claim (Index 21):
A method of forming an integrated circuit, comprising:\n forming first and second doped regions of a first conductivity type within a semiconductor substrate of the first conductivity type; forming a third doped region of a second conductivity type located within the substrate between the first and second doped regions; forming a fourth doped region of the first conductivity type at a surface of the substrate and located between and connected to the first doped region and the third doped region; forming a gate electrode over the third doped region; and forming a buried layer having the second conductivity type within the substrate, the third doped region located between the buried layer and the gate electrode, the buried layer partially extending from the third doped region toward the first doped region, wherein the second doped region and the buried layer are spaced apart laterally.
