Abstract

A pMOS device with an embedded silicon-controlled rectifier to improve its electrostatic discharge (ESD) robustness has been proposed and implemented in a 28-nm high-k/metal gate CMOS process. An additional p-type ESD implantation layer was added into the pMOS to realize the proposed device. The experimental results show that the proposed device has the advantages of high ESD robustness, low holding voltage, low parasitic capacitance, and good latchup immunity. With better performances, the proposed device was more suitable for ESD protection in a sub-50-nm CMOS process.
