Abstract:
A semiconductor device is proposed. The semiconductor device includes a source region of a field effect transistor having a first conductivity type, a body region of the field effect transistor having a second conductivity type, and a drain region of the field effect transistor having the first conductivity type. The source region, the drain region, and the body region are located in a semiconductor substrate of the semiconductor device and the body region is located between the source region and the drain region. The drain region extends from the body region through a buried portion of the drain region to a drain contact portion of the drain region located at a surface of the semiconductor substrate, the buried portion of the drain region is located beneath a spacer doping region, and the spacer doping region is located within the semiconductor substrate.

Claim (Index 19):
A method for forming a semiconductor device, the method comprising:\n forming a drain region of a field effect transistor of the semiconductor device having a first conductivity type and having a buried portion; forming a body region of the field effect transistor having a second conductivity type; and forming a source region of the field effect transistor having the first conductivity type, wherein the source region, the drain region, and the body region are positioned in a semiconductor substrate of the semiconductor device, wherein the body region is positioned between the source region and the drain region, wherein the drain region extends from the body region to a drain contact portion of the drain region, the drain contact portion positioned at a surface of the semiconductor substrate, wherein a current path of the field effect transistor extends in the drain region from the body region through the buried portion to the drain contact portion, wherein the buried portion of the drain region is positioned beneath a spacer doping region, wherein the spacer doping region is positioned within the semiconductor substrate, wherein the spacer doping region and the body region are portions of a well doping region having the second conductivity type.
