High performance N- and P-type gate-all-around nanowire MOSFETs fabricated on bulk Si by CMOS-compatible process
We demonstrate high performance silicon nanowire gate-all-around MOSFETs (SNWFETs) fabricated on bulk Si by a novel top-down CMOS-compatible method. The fabricated N- and P-type SNWFETs of sub-50 nm gate length and of ∼5 nm in diameter show excellent short channel effects (SCEs) immunity with subthreshold slope (SS) of 90/69 mV/dec, DIBL of 47/10 mV/V, and high driving current of 2×103/5.4×103 µA/µm at 0.1 nA/µm off-current.
