    摘要: Methods and apparatus of forming titanium tantalum silicon nitride (TixTay(Si)Nz) layers are described. The titanium tantalum silicon nitride (TixTay(Si)Nz) layer may be formed using a cyclical deposition process by alternately adsorbing a titanium-containing precursor, a tantalum-containing precursor, a nitrogen-containing gas and a silicon-containing gas on a substrate. The titanium-containing precursor, the tantalum-containing precursor, the silicon-containing precursor and the nitrogen-containing precursor react to form the titanium tantalum silicon nitride (TixTay(Si)Nz) layer on the substrate. The formation of the titanium tantalum silicon nitride (TixTay(Si)Nz) layer is compatible with integrated circuit fabrication processes. In one integrated circuit fabrication process, the titanium tantalum silicon nitride (TixTay(Si)Nz) layer is used as a diffusion barrier for a copper metallization process.

    摘要: The present invention generally relates to filling of a feature by depositing a barrier layer, depositing a seed layer over the barrier layer, and depositing a conductive layer over the seed layer. In one embodiment, the seed layer comprises a copper alloy seed layer deposited over the barrier layer. For example, the copper alloy seed layer may comprise copper and a metal, such as aluminum, magnesium, titanium, zirconium, tin, and combinations thereof. In another embodiment, the seed layer comprises a copper alloy seed layer deposited over the barrier layer and a second seed layer deposited over the copper alloy seed layer. The copper alloy seed layer may comprise copper and a metal, such as aluminum, magnesium, titanium, zirconium, tin, and combinations thereof. The second seed layer may comprise a metal, such as undoped copper. In still another embodiment, the seed layer comprises a first seed layer and a second seed layer. The first seed layer may comprise a metal, such as aluminum, magnesium, titanium, zirconium, tin, and combinations thereof. The second seed layer may comprise a metal, such as undoped copper.

    摘要: During a deposition process, material may deposit not only on the substrate, but also on other chamber components. In a MOCVD chamber, one of those components is the gas distribution showerhead. The showerhead may be cleaned by bombarding the showerhead with radicals generated by a plasma that includes an inert gas and chlorine. In order to generate the plasma, the showerhead may be negatively biased or floating relative to the substrate support. The showerhead may comprise stainless steel and be coated with a ceramic coating.
