Abstract: An electrostatic discharge protection circuit is disclosed. A method of manufacturing a semiconductor structure includes forming a semiconductor controlled rectifier including a first plurality of fingers between an n-well body contact and an anode in an n-well, and a second plurality of fingers between a p-well body contact and a cathode in a p-well.
