Patent ID: 8530963

Claim:
A semiconductor device comprising: a semiconductor material; an active area; a transistor including: a gate over a first surface of the semiconductor material; a source region in the active area; a drain region; a source electrode coupled to the source region; a drain electrode coupled to the drain region; and a channel region disposed between the source region and the drain region, wherein the channel region has an approximately constant doping profile; a first layer of conductive material positioned over the first surface of the semiconductor material and adjacent to a portion of the gate of the transistor; and a dielectric structure extending from the first surface of the semiconductor material into the semiconductor material, wherein at least a portion of the first layer of conductive material is positioned over the dielectric structure, wherein the dielectric structure is at least partially disposed between the first layer of conductive material and the drain region; and wherein the dielectric structure includes a plurality of vertically extending dielectric structures separated by one or more cavities.
