ABSTRACT:
A PMOS ESD protection device is disclosed in which gate and substrate coupling techniques are implemented to afford protection during positive ESD events. A snapback leg in curves capable of being produced in accordance with one or more aspects of the present invention is removed, and a trigger voltage at which the device turns on is thereby reduced so as to be less than a second voltage corresponding to a second breakdown region.
