Abstract:
1. An electrostatic discharge protection device formed on a substrate, comprising: a first isolation region formed over the substrate; an active region formed over the substrate and enclosed by the first isolation region; a second isolation region formed on the substrate and substantially surrounded by the active region; a first gate element formed in the active region, having a first end overlapping a first edge of the first isolation region and a second end overlapping a second edge of the second isolation region; a drain region formed in the active region at a first side of the first gate element; a source region formed in the active region at a second side of the first gate element a drain contact for electrically coupling the drain region to a first node; and a source contact for electrically coupling the source region to a second node; wherein the second isolation region forms a peninsula structure extending from the first isolation region and is partially surrounded by the active region.
