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 either
conductivity type, the first trigger contact disposed at a junction
between the first well and the second well, and the second trigger
contact disposed at either well.
