Abstract
Official abstract text for this publication.
An electrostatic discharge protection clamp adapted to limit a voltage appearing across protected terminals of an integrated circuit to which the electrostatic discharge protection clamp is coupled is presented. The electrostatic discharge protection clamp includes a substrate, and a first electrostatic discharge protection device formed over the substrate. The first electrostatic discharge protection device includes a buried layer formed over the substrate, the buried layer having a first conductivity type and defining an opening located over a region of the substrate, a first transistor formed over the opening of the buried layer, the first transistor having an emitter coupled to a first cathode terminal of the electrostatic discharge protection clamp, and a second transistor formed over the buried layer, the second transistor having an emitter coupled to a first anode terminal of the electrostatic discharge protection clamp.
