    摘要: Methods, apparatus, and systems for depositing copper and other metals are provided. In some implementations, a wafer substrate is provided to an apparatus. The wafer substrate has a surface with field regions and a feature. A copper layer is plated onto the surface of the wafer substrate. The copper layer is annealed to redistribute copper from regions of the wafer substrate to the feature. Implementations of the disclosed methods, apparatus, and systems allow for void-free bottom-up fill of features in a wafer substrate.

    摘要: Method and apparatus for reducing metal oxide surfaces to modified metal surfaces are disclosed. Metal oxide surfaces are reduced to form a film integrated with a metal seed layer by contacting a solution with a reducing agent with the metal oxide surfaces. The solution with the reducing agent can contact the metal oxide surfaces under conditions that form an integrated film with the metal seed layer, and that reduces reoxidation from exposure the ambient environment. In some embodiments, an additive can be included with the reducing agent to form a surface protecting layer on the metal seed layer. In some embodiments, the metal is copper used in damascene copper structures.
