Patents by Inventor Jean L. Sweet

Jean L. Sweet has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10147680
    Abstract: Various methods and semiconductor structures for fabricating at least one FET device having textured gate-source-drain contacts of the FET device that reduce or eliminate variability in parasitic resistance between the contacts of the FET device. An example fabrication method includes epitaxially growing a source-drain contact region on an underlying semiconductor substrate of one of a pFET device or an nFET device. The method deposits a bottom film layer directly on the epitaxially grown source-drain contact region. A first anneal forms a textured bottom silicide film layer directly on the epitaxially grown source-drain contact region. A top metal film layer is deposited on the textured bottom silicide film layer. A second anneal forms a textured top metal silicide film layer. The method can be repeated on the other one of the pFET device or the nFET device.

An example fabrication method includes epitaxially growing a source-drain contact region on an underlying semiconductor substrate of one of a pFET device or an nFET device. The method deposits a Nickel film layer directly on the epitaxially grown source-drain contact region. A first anneal forms a textured Nickel silicide film layer directly on the epitaxially grown source-drain contact region. A second metal film layer is deposited on the textured Nickel silicide film layer. A second anneal forms a textured second metal silicide film layer. The method can be repeated on the other one of the pFET device or the nFET device.
