SCR Devices in ESD Protection Circuits for CMOS IC's

Electrostatic discharge is considered a serious threat to CMOS IC's.With the scaling down of CMOS technology,the demand for ESD protection has become stronger than ever before.In recent years,SCR devices are widely used in CMOS IC's for ESD protection.ESD protection circuits using SCR devices are reviewed in the paper,to provide IC designers with a reference in dealing with ESD protection design for CMOS integrated circuits.
