Patent ID: 7601990

Claim:
An electrostatic discharge protection device, comprising: an interconnect region having a first interconnect and a second interconnect; a dynamic region including an Nwell region contacting the first interconnect, and a Pwell region contacting the second interconnect, wherein the Nwell region includes a first N+ contact, a first P+ contact and a N+ doped enhancement, wherein the Pwell region includes a second N+ contact, a second P+ contact and a P+ doped enhancement, and wherein the N+ doped enhancement is positioned in contact with the P+ doped enhancement forming a breakdown voltage region therebetween; and a platform region including a P-doped substrate situated adjacent to the Nwell region and the Pwell region; wherein at least one of a breakdown voltage and an NPN critical current, measured from the first interconnect to the second interconnect, is set independently, wherein the breakdown voltage between the first and second interconnect region is determined by at least one of the doping of the N+ doped enhancement, the doping of the P+ doped enhancement, and an amount of contact area of the N+ doped enhancement with the P+ doped enhancement, and wherein the NPN critical current is determined by a width of the second N+ contact multiplied by the Pwell sheet resistance adjacent to the second N+ contact.
