Abstract

An electrostatic discharge (ESD) device and method is provided. The ESD device can comprise a substrate doped to a first conductivity type, an epitaxial region doped to the second conductivity type, and a first well doped to the first conductivity type disposed in the substrate. The first well can comprise a first region doped to the first conductivity type, a second region doped to a second conductivity type, and a first isolation region disposed between the first region and the second region. The ESD device can also comprise a second well doped to a second conductivity type disposed in the substrate adjacent to the first well, where the second well can comprise a third region doped to the first conductivity type, a fourth region doped to the second conductivity type, and a second isolation region disposed between the third region and the fourth region. Still further, the ESD device can include a first trigger contact and second trigger contact comprising highly doped regions of eithe
