Sub-100 nm InGaAs quantum-well (QW) tri-gate MOSFETs with Al2O3/HfO2 (EOT < 1 nm) for low-power logic applications

This paper reports tri-gate sub-100 nm In0.53Ga0.47As QW MOSFETs with electrostatic immunity of S = 77 mV/dec., DIBL = 10 mV/V, together with excellent carrier transport of gm, max &gt; 1.5 mS/μm, at VDS = 0.5 V. This result is the best balance of gm, max and S in any reported III-V MOSFETs. In addition, extracted compact model parameter including (μ0 = 760 cm2/V-s and peak vx0 = 1.6&#215;107 cm/s) indicate that InGaAs Tri-Gate MOSFETs would be a viable pathway to sub-10nm technology node.
