Patent ID: 8592906

Claim:
A semiconductor device comprising: a semiconductor substrate; a source region disposed within the semiconductor substrate; a drain region disposed within the semiconductor substrate; a field shaping region disposed within the semiconductor substrate and disposed between the source region and the drain region, the field shaping region including: an insulator; and a plurality of conductive plates disposed within the insulator, each of the plurality of conductive plates being electrically insulated from other of the plurality of conductive plates by the insulator and electrically insulated from the semiconductor substrate by the insulator; and an active region disposed within the semiconductor substrate and disposed between the source region and the drain region, the active region being aligned in parallel with the field shaping region, the active region and the field shaping region being aligned in a direction of current flow in the active region when the semiconductor device is biased in a conducting state, the field shaping region being disposed in the active region.
