Abstract
A one-step plasma treatment for improving the laminate adhesion of metallic and non-metallic substrates is described. The treatment comprises forming a plasma of a polar containing organic species and at least one of nitrogen and hydrogen and exposing a substrate material to the plasma for a period of time sufficient to deposit a polymeric film on at least one surface. In a preferred embodiment, a plasma of an azole, nitrogen and/or hydrogen is utilized. The process has particular utility in forming adherent polymeric films on one or more surfaces of copper and copper alloy foils to be used in printed circuit applications.
