Abstract

This paper demonstrates the integration of a composite high-κ gate stack (3.3 nm Al₂O₃-1.0 nm GaSb) with a mixed anion InAs_0.8Sb_0.2 quantum-well field effect transistor (QWFET). The composite gate stack achieves; (i) EOT of 4.2 nm with <10 ^-7A/cm² gate leakage (ii) low D_it interface (∼1x10¹² /cm²/eV) (iii) high drift μ of 3,900-5,060 cm²/V-s at NS of 5×10¹¹-3×10 ¹²/cm². The InAs_0.8Sb_0.2 MOS-QWFETs with composite gate stack exhibit extrinsic (intrinsic) g_m of 334 (502) μS/μm and drive current of 380 μA/μm at V_DS = 0.5V for Lg=1μm.
