Patent ID: 7534555

Claim:
A method for plating, comprising: coating a substrate with a barrier layer, wherein the barrier layer comprises an adhesive composition comprising a polyphenolic polymer, said polyphenolic polymer comprising repeating monomeric units having the formula: wherein each of R 1 , R 2 , R 3 , R 4 , and R 5 are each individually a hydroxy group, hydrogen, or an azo dye moiety; coating the barrier layer with a top layer comprising a photoresist; imagewise exposing the top layer to radiation; removing a portion of the top layer for exposing a portion of the barrier layer; removing the exposed portion of the barrier layer for exposing a portion of the substrate, wherein removal of the exposed portion of the barrier layer does not create undercuts under the photoresist; and plating a material on the exposed portion of the substrate.
