Abstract

This invention is directed to a process for the selective metallization which utilizes multiple photoresist layers, using a buried palladium ligand which is then catalyzed using a PdBr selective catalyst. The Pd in the catalyst is then reduced to Pd.sup.0 and metallized using for example electroless copper.
