摘要: The operation principles of gate-driven design and substrate-triggered design for ESD (ElectroStatic Discharge) protection are first explained by energy-band diagrams in this paper. The on-chip ESD protection devices realized in 0.18-mum and 0.35-mum CMOS processes are used to verify the efficiency of gate-driven or substrate-triggered designs. The substrate-triggered design can effectively and continually improve ESD robustness of protection devices than the gate-driven design. The HEM (Human-Body-Model) ESD level of NMOS with a W/L of 300 mum/0.3 mum can be improved from the original 0.8kV to become 3.3kV by the substrate-triggered design. But, the gate-driven design cannot continually improve the ESD level of the same device in the subquarter-micron CMOS process.
