Abstract
A three-step plasma treatment for improving the laminate adhesion of metallic and non-metallic substrates is described. The treatment comprises sequentially exposing the substrate to a first plasma of oxygen gas, a second plasma of a hydrocarbon monomer gas and a third plasma of oxygen gas. The process has particular utility in forming polymeric films on one or more surfaces of copper or copper alloy foils to be used in printed circuit applications.
