Abstract

The present invention provides an ESD device to reduce the total triggering current without increasing the overshoot voltage. This is achieved by localizing the triggering current, such that the local current density remains high enough to trigger the ESD device. This localized triggering provides a fast and efficient triggering of the ESD device.
