We demonstrate undoped-body, gate-all-around (GAA) Si nanowire (NW) MOSFETs with excellent electrostatic scaling. These NW devices, with a TaN/Hf-based gate stack, have high drive-current performance with NFET/PFET IDSAT 825/950 μA/μm (circumference-normalized) or 2592/2985 μA/μm (diameter-normalized) at supply voltage VDD = 1 V and off-current IOFF = 15 nA/μm. Superior NW uniformity is obtained through the use of a combined hydrogen annealing and oxidation process. Clear scaling of short-channel effects versus NW size is observed. ©The Electrochemical Society.
