  • Diode chain with guard-band
    Patent number: 8537514
    Abstract: The present invention provides an ESD protection device having at least one diode in a well of first conductivity type formed in a substrate of second conductivity type. The circuit further includes a guard-band of the first conductivity surrounding at least a portion of the diode, thus forming an NPN transistor between the diode cathode, the substrate and the guard-band.
    Type: Grant

  • Localized trigger ESD protection device
    Patent number: 7973334
    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.
