  • Patent number: 10832959
    Abstract: A semiconductor device includes a n-type gate structure over a first semiconductor fin, in which the n-type gate structure is fluorine incorporated and includes a n-type work function metal layer overlying the first high-k dielectric layer. The n-type work function metal layer includes a TiAl (titanium aluminum) alloy, in which an atom ratio of Ti (titanium) to Al (aluminum) is in a range substantially from 1 to 3. The semiconductor device further includes a p-type gate structure over a second semiconductor fin, in which the p-type gate structure is fluorine incorporated includes a p-type work function metal layer overlying the second high-k dielectric layer. The p-type work function metal layer includes titanium nitride (TiN), in which an atom ratio of Ti to N (nitrogen) is in a range substantially from 1:0.9 to 1:1.1.
    Type: Grant

  • Patent number: 9449922
    Abstract: In a method for manufacturing a semiconductor device, a dielectric layer is formed on a substrate, and a contact hole is formed from the dielectric layer to the substrate. A dielectric spacer liner is formed to cover a sidewall and a bottom of the contact hole. A portion of the dielectric spacer liner is removed to expose a portion of the substrate. A metal silicide layer is formed into the substrate through the contact hole.
