Claim Text:
1. A semiconductor device comprising: an active device region containing a plurality of active devices; and a termination structure that surrounds the active device region, wherein the termination structure includes a first conductive region that surrounds the active device region, an insulator region that surrounds the first conductive region, and a second conductive region that surrounds the first conductive region and the insulator region, wherein the active device region and termination structure are formed into a semiconductor material of a first conductivity type, wherein the first conductive region is electrically connected to a gate metal and the second conductive region is connected to a drain metal; and a termination shield formed between the first and second conductive regions, wherein the termination shield is electrically isolated from the first and second portions of conductive material, and wherein the termination shield is maintained at a source potential.
