    摘要: A method is provided for forming a metal silicide layer on a substrate. According to one embodiment the method includes providing the substrate in a process chamber, exposing the substrate at a first substrate temperature to a plasma generated from a deposition gas containing a metal precursor, where the plasma exposure forms a conformal metal-containing layer on the substrate in a self-limiting process. The method further includes exposing the metal-containing layer at a second substrate temperature to a reducing gas in the absence of a plasma, where the exposing steps are alternatively performed at least once to form the metal silicide layer, and the deposition gas does not contain the reducing gas. The method provides conformal metal silicide formation in deep trenches with high aspect ratios.

    摘要: A method for forming an aluminum-doped metal (tantalum or titanium) carbonitride gate electrode for a semiconductor device is described. The method includes providing a substrate containing a dielectric layer thereon, and forming the gate electrode on the dielectric layer in the absence of plasma. The gate electrode is formed by depositing a metal carbonitride film, and adsorbing an atomic layer of an aluminum precursor on the metal carbonitride film. The steps of depositing and adsorbing may be repeated a desired number of times until the aluminum-doped metal carbonitride gate electrode has a desired thickness.

    摘要: A high conductance, multi-tray solid precursor evaporation system coupled with a high conductance vapor delivery system is described for increasing deposition rate by increasing exposed surface area of solid precursor. The multi-tray solid precursor evaporation system includes a base tray with one or more upper trays. Each tray is configured to support and retain film precursor in, for example, solid powder form or solid tablet form. Additionally, each tray is configured to provide for a high conductance flow of carrier gas over the film precursor while the film precursor is heated. For example, the carrier gas flows inward over the film precursor, and vertically upward through a flow channel within the stackable trays and through an outlet in the solid precursor evaporation system.
