Abstract

InGaAs FinFETs fabricated by an unique Si fin replacement process have been demonstrated on 300mm Si substrates. The devices are integrated by process modules developed for a Si-IIIV hybrid 300mm R&D pilot line, compatible for future CMOS high-volume manufacturing. First devices with a SS of 190 mV/dec and extrinsic gm of 558 μS/μm are achieved for an EOT of 1.9nm, Lg of 50nm and fin width of 55nm. A trade-off between off state leakage and mobility for different p-type doping levels of the InP and InGaAs layers is found and the RMG high-κ last processing is demonstrated to offer significant performance improvements over that of high-κ first.
