Abstract
Methods and devices are provided for protecting semiconductor devices against electrostatic discharge events. An electrostatic discharge protection device comprises a silicon substrate, a P-type anode region disposed within the silicon substrate, and an N-well device region disposed within the silicon substrate in series with the P-type anode region. A first P-well device region is disposed within the silicon substrate in series with the first N-well device region and an N-type cathode region is disposed within the silicon substrate. A gate electrode is disposed at least substantially overlying the first N-well and P-well device regions of the silicon substrate.
