    Abstract: A method for forming nickel silicide includes degassing a semiconductor substrate that includes a silicon surface. After the degassing operation, the substrate is cooled prior to a metal deposition process, during a metal deposition process, or both. The cooling suppresses the temperature of the substrate to a temperature less than the temperature required for the formation of nickel silicide. Nickel diffusion is minimized during the deposition process. After deposition, an annealing process is used to urge the formation of a uniform silicide film. In various embodiments, the metal film may include a binary phase alloy containing nickel and a further element.

    Abstract: Semiconductor devices and fabrication methods thereof. An opening is formed in a first dielectric layer, exposing an active region of the transistor, and an tungsten-containing barrier is conformably formed in the opening, with a thickness less than 50 Å. A tungsten layer is formed over the atomic layer deposited (ALD) tungsten-containing barrier to fill the opening.
