A combined adhesion promotion and direct metallization process

摘要

A combined adhesion promotion method of a metal to a non-conductive substrate and directly metallizing the non-conductive substrate with the metal. The method involves texturing a non-conductive substrate with a cobalt etch followed by applying a sulfide to the textured non-conductive substrate to provide an electrically conductive surface on the non-conductive substrate. After the surface of the non-conductive substrate has been made electrically conductive, the surface of the non-conductive substrate can be directly metallized. The method reduces the number of process steps for direct metallization of a non-conductive substrate. Thus, the method is more efficient in contrast to conventional methods of metallizing a non-conductive substrate.
