Abstract
An SCR-buried BJT with a high holding voltage is developed for ESD protection in a 0.6 mum high voltage 10 V process. This device simply consists of a floating P+ diffusion buried in a parasitic NPN BJT. A robust 6~7KV ESD threshold and high-latchup-immune 15~18V holding voltage can be achieved by layout optimization of the anode-to-floating- P+-diffusion spacing and this P+ diffusion width.
