ABSTRACT:
An SCR circuit formed on a semiconductor substrate includes a well region, a first diffusion region and a second diffusion region in the well region, and a third diffusion region in the substrate. The SCR circuit also includes a capacitor connected between the first diffusion region and the third diffusion region. The junction region between the well region and the diffusion region is forward biased when an electrostatic force is applied to the SCR circuit, thereby triggering the SCR circuit to discharge the electrostatic force.
