Popis: This paper reports on gate-last (GL) In 0.7 Ga 0.3 As QW MOSFETs with regrown S/D by MOCVD. Long-channel devices exhibit excellent electrostatics and carrier transport (SS=80mV/dec., DIBL=22mV/V, and μ n,eff >5,500 cm 2 /V-s at 300k). Short-channel device with L g = 40 nm also exhibit excellent electrostatic integrity of SS = 105 mV/dec., and DIBL = 150 mV/V, together with g m_max = 2 mS/μm at V DS = 0.5 V. This record performance is achieved by using a low D it and Al 2 O 3 /HfO 2 gate stack with EOT ~ 1-nm, optimized selective S/D regrowth with MOCVD, and GL process.
