  • Patent number: 7504329
    Abstract: Low work function metals for use as gate electrode in nMOS devices are provided. The low work function metals include alloys of lanthanide(s), metal and semiconductor. In particular, an alloy of nickel-ytterbium (NiYb) is used to fully silicide (FUSI) a silicon gate. The resulting nickel-ytterbium-silicon gate electrode has a work function of about 4.22 eV.
    Type: Grant
    Filed: May 11, 2006
    Date of Patent: March 17, 2009
    Assignees: Interuniversitair Microelektronica Centrum (IMEC), National University of Singapore (NUS), Texas Instruments Incorporated
