Abstract:
1. A process for metallizing a surface of a dielectric substrate with electrolytically plated copper metallization, the process comprising: contacting the dielectric substrate with an initiator composition comprising an oxidant to thereby form an oxide film on the surface of the dielectric substrate; contacting the surface of the dielectric substrate having the oxide film thereon with a catalyst composition comprising at least one heterocyclic aromatic molecule for forming an electrically conductive polymer on the oxide film on the surface of the dielectric substrate, an acid, and a source of Mn(II) ions in an amount sufficient to provide an initial concentration of Mn(II) ions of at least about 0.85 g/L to form an electrically conductive polymer on the oxide film on the surface of the dielectric substrate; contacting the surface of the dielectric substrate having the oxide film and electrically conductive polymer thereon with an electrolytic deposition composition comprising a source of copper ions and an acid; and supplying an external source of electrons to electrolytically depositing copper from said electrolytic deposition composition over said electrically conductive polymer.
