Patent ID: 10304938

Abstract:
Various methods and semiconductor structures for fabricating an FET device having Nickel atoms implanted in a silicide metal film on a source-drain contact region of the FET device thereby reducing resistance of the source-drain contact region of the FET device. An example fabrication method includes maskless blanket implantation of Nickel atoms across a semiconductor wafer. Nickel atoms can be implanted into silicide metal film of a source-drain contact region of nFET devices, pFET devices, or both, on a semiconductor wafer. Nickel atoms can be implanted into silicide metal film on a source-drain contact region of nFET devices and pFET devices. The silicide metal film on the source-drain contact region of the nFET device being a different material than the silicide metal film on the source-drain contact region of the pFET device.
