  • Bi-directional silicon controlled rectifier structure with high holding voltage for latchup prevention
    Patent number: 6960792
    Abstract: A bi-directional silicon controlled rectifier structure provides electrostatic discharge (ESD) protection against both positive and negative voltage spikes. The structure utilizes a pair of wells, n+ and p+ regions formed in both wells, a first ring formed around the junction between the first well and the semiconductor material, and a second ring formed around the junction between the second well and the semiconductor material.
