Evaluation of SCR-based ESD protection devices in 90nm and 65nm CMOS technologies

We compare a number of promising SCR-based ESD protection devices in 90nm and 65nm CMOS technologies implemented with a consistent layout. The devices are evaluated using ESD metrics such as trigger voltage and current, on-resistance, failure current, turn-on time and DC leakage current. We also report that SCR turn-on time is highly dependent on the amplitude of the applied pulse. © 2007 IEEE.
