    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallic source drain; contact resistivity; Monte Carlo; NiSi; PtSi; SOI; UTB; tri-gate; FinFET; multiple-gate; nanowire; MOSFET; CMOS; Schottky barrier; silicide; SALICIDE;

    Abstract : As scaling of CMOS technology continues, the control of parasitic source/drain (S/D) resistance (RSD) is becoming increasingly challenging. In order to control RSD, metallic source/drain MOSFETs have attracted significant attention, due to their low resistivity, abrupt junction and low temperature processing (≤700 °C). READ MORE
