An on-chip combo clamp for surge and universal ESD protection in bulk FinFET technology

A surge protection consisted of the ready-made ESD clamp transistors has been designed and characterized in FINFET technology. It can endure all the stresses from CDM, HBM and Surge events. Compared to a conventional 0.7V RC-based core ESD clamp, the proposed cell greatly boosts the Surge immunity from 4V to 19V.
