5nm-gate nanowire FinFET
2004
A new nanowire FinFET structure is developed for CMOS device scaling into the sub-10 nm regime. Accumulation mode P-FET and inversion mode N-FET with 5 nm and 10 nm physical gate length, respectively, are fabricated. N-FET gate delay (CV/I) of 0.22 ps and P-FET gate delay of 0.48 ps with excellent subthreshold characteristics are achieved, both with very low off leakage cur-rent less than 10 nA/ /spl mu/m. Nanowire FinFET device operation is also explored using 3-D full quantum mechanical simulation.
