    摘要: Methods and systems for cleaning corrosion product of a metallic layer from the surface of a substrate are provided. According to one embodiment, a treatment solution includes a surfactant, a complexing agent, and a pH adjuster. The surfactant is configured to enhance wetting of the substrate surface, and inhibit further corrosion of the capping layer. The complexing agent is configured to bind to metal ions which have desorbed from the substrate surface. The pH adjuster is configured to adjust the pH to a desired level, so as to promote desorption of the corrosion product from the substrate surface.
