High-Voltage Electrostatic Discharge Protection Device development in 28nm BCDLite Technology

Best-in-class (BIC) High-Voltage (HV) Electrostatic Discharge (ESD) solutions for 8-12V power pad protection in first-of-its-kind GlobalFoundries ^® 28nm low-cost BCDLite process are evaluated. A comparative analysis between different types of devices, namely gate-grounded NMOS (GGNMOS), NPN, PNP and Diode, showing DC & 100ns Transmission Line Pulse (TLP) performance from Technology Computer-Aided Design (TCAD) simulations and silicon measurement results with performance metrics in terms of core device ESD protection effectiveness w.r.t Safe Operating Area (SOA) boundary and key Figures of Merit (FOMs) is elucidated.
