Abstract :
An ESD clamp protection structure with current mirror for capacitor boosting was proposed in this paper. For the power rail protection, silicon-control-rectifier (SCR) is a better choice than the BIGFET as main ESD clamp device, which can provide better ESD robustness with smaller area and lower leakage current. The area of protection structure is reduced further for the utility of capacitor boosting technique. The trigger performance of the power rail clamp device was verified in the commercial CMOS process with featured size of 0.18°m. The total area of 50°m×50°m was achieved. The failure phenomenon in the measurement was also discussed for further improvement in this paper.
