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 28):
A method of forming an integrated circuit, comprising:\n forming a source region and a drain region having a first conductivity type in a semiconductor substrate having the first conductivity type; forming a buried layer having a second conductivity type that extends under the source region and the drain region; forming a first well region having the second conductivity type that extends from the source region to the buried layer; and forming a second well region of the first conductivity type in the semiconductor substrate spaced apart from the first well region, wherein a semiconductor substrate portion is located between the second well region and the buried layer, the substrate portion having a lower dopant concentration than the second well region.
