A Novel and Robust Un-Assisted, Low-Trigger and High-Holding Voltage SCR (uSCR) for Area-Efficient On-Chip ESD Protection

摘要

A novel and robust un-assisted low-trigger and high-holding voltage silicon controlled rectifier (uSCR) is proposed and realized in a 0.35-mum fully-salicided BiCMOS process. Without using any external trigger circuitry, the uSCR has a trigger voltage as
