Abstract :
A new electrostatic discharge (ESD) protection circuit based on a standard of 0.6 ¿m CMOS p-well technology has been designed and fabricated according to the request of trigger voltage, chip area and static current to high-speed CMOS IC. The new protection circuit was verified by a multi-project wafer (MPW) fabrication and tested by the transmission line pulse (TLP) generator system. The results show that new ESD protection circuit has lower trigger voltage, smaller chip area and a higher ESD failure voltage compared with those of gate grounded NMOS (ggNMOS) protection circuits with the same MPW. The voltage up to 5 KV under human-body mode (HBM) test has been obtained.
