Abstract :
Four new device structures for power-rail ESD clamp circuits by using the substrate-triggering technique are investigated in submicron CMOS technology to improve ESD level of the protection device within a smaller silicon area. Experimental results in a 0.6-μm CMOS process have verified that the ESD clamp circuit with the double-BJT structure can provide 200% higher ESD robustness in per unit layout area as comparing to the previous design with the NMOS device
