Patent ID: 7154150

Claim:
An electro-static discharge (ESD) protection device comprising: a) a first n+ region and a second n+ region separated by a first isolation region in a substrate; said substrate is p− doped; b) a first n − well overlapping a portion of said first isolation region and overlapping a portion of said first n+ region; c) a first p+ region adjacent to, but not contacting said second n+ region; d) a second n− well overlapping a portion of said first p+ region and all of said second n+ region; said second n+ region abutting said first isolation region; said second n− well overlapping a portion of said first isolation region; said second n− well between said first p+ region and said second n+ region; e) a third n+ region separated from said first p+ region by a portion of said substrate; f) a first gate on said first isolation region; g) said third n+ region, said first p+ region, and said second n+ region connected in parallel to a source; and h) silicide regions over the first, second and third n+ regions and the first p+ region.
