Short gate-length Pt full-silicidation (FUSI) (PtSi and Pt2 Si) pMOSFETs were fabricated for the first time using a self-aligned Pt-FUSI process, demonstrating scalability (with no linewidth effects) down to ~ 60-nm gate lengths. The electrical results are compared to the Ni-FUSI (NiSi and Ni31Si12) pMOSFET devices. A low threshold voltage les|-0.29 V| was obtained for the Pt2Si-FUSI pMOSFETs on SiON and HfSiON indicating that the Pt2Si FUSI does not suffer from the Fermi-level pinning or gate-dielectric-charge effects on the HfSiON
