Abstract
Silicon-controlled rectifiers, electrostatic discharge circuits, and methods of fabricating a silicon-controlled rectifier for use in an electrostatic discharge circuit. A device structure for the silicon controlled rectifier includes a first well of a first conductivity type in a semiconductor layer, a second well of a second conductivity type in the semiconductor layer, a cathode coupled with the first well, and an anode coupled with the second well. First and second body contacts are coupled with the first well, and the first and second body contacts each have the first conductivity type. A triggering device may be coupled with the first body contact.
