Patent ID: 7385273

Claim:
A power semiconductor device comprising: an active region, said active region including a plurality of gate structures each having a gate insulation of a first thickness; a termination region, said termination including a field insulation body surrounding said active region, said field insulation body having a recess formed therein said recess having a bottom insulation of a second thickness that is thicker than said first thickness; a conductive body formed in said field insulation body having a recess formed therein having a on said bottom insulation; a field plate structure adjacent said field insulation body and disposed between said active region and said recess, said field plate structure including a field plate insulation body thicker than said first thickness, and a conductive field plate body disposed over said field plate insulation body; and a PN junction region extends from under said recess having said bottom insulation, below said field plate structure and into said active region.
