Patent ID: 7605431

Claim:
An electrical static damage protection device comprising: a substrate; a first device region formed in the substrate, the first device region including: a first doped region of a first dopant type; a first well region of the first dopant type spaced apart from the first doped region; a second doped region of the first dopant type located in the first well region; a third doped region of a second dopant type located outside the first well region and adjacently between the first and second doped region; a second device region formed in the substrate spaced apart from the first device region, the second device region including: a second well region of the first dopant type; a fourth doped region of the second dopant type formed in the second well region; a fifth doped region of the first dopant type located in the second well region and spaced apart from the fourth doped region; a sixth doped region of the second dopant type outside the second well region, wherein the fifth doped region is located adjacently between the fourth and sixth doped region; and an electrical wiring coupled with the first and second device region for forming a shunt circuit adapted to discharge electrical static charges.
