Analysis of SCR based ESD Protection Circuit with High Robustness for Low Voltage Application

Abstract
Thisstudyproposes the robust SCR-based ESD protection circuit with fast turn-on speed for low voltage application. The proposed circuit has the additional P-well and P+ region that forms the additional parasitic PNP BJT in parallel.To evaluate the electrical properties, the simulation is conducted by the Synopsys TCAD simulator. The simulation results show that the proposed circuit has the fast turn-on time and high ESD robustnesscompared with the PTSCR(PSubstrate Triggered SCR). Keywords - ESD(Electro-Static Discharge), SCR(Silicon Controlled Rectifier), I/O Clamp.
