Abstract :
Bipolar SCR devices are studied as a potential ESD protection solution in case of a hi-voltage (250V) process. The problem of the HBM-TLP (human body model pulse-transmission line pulse) correlation is discussed based on pulsed measurements, ESD characterization and TCAD analysis, and is followed by a suggested new solution, based upon a multi-stage network and engineered to eliminate residual high turn-off voltage.
