Abstract :
An ultra-low trigger gate-bounded SCR using a high-k metal gate process is proposed, which has a superb immunity to protect thin oxide against CDM-like stresses without a resistor in series. This cell is fast triggered by the channel current injection and can meet the low leakage and capacitance requirements for highspeed I/O circuits.
