Synchrotron radiation processing of a surface to be metallised

摘要

Method of seeding a substrate surface to be metallised, especially by electroless plating, in which the surface is coated with a layer of a substance, such as palladium acetate, which can furnish seeds or nucleation sites for a chemical deposition of metal, such as copper, and which substance is decomposed by synchrotron radiation of an intensity which effects a substantially photolytic but not thermal decomposition of the substance.
