Abstract :
Technology scaling data are presented based on 65 nm, 45 nm, and the 32 nm high-K, metal gate process. Thin oxide NFET parasitic bipolar snapback and gate dielectrics breakdown voltages decrease to 3.2V and 3.6V, respectively. The top concern is to achieve adequate voltage clamping at I/O pads. Continuous improvement in ESD device failure currents per area is found. Vertical metal wiring schemes are needed to overcome wiring resistance challenges.
