Abstract: An etching solution for copper and copper alloy surfaces comprising at least one acid, at least one oxidising agent suitable to oxidise copper, at least one source of halide ions and further at least one polyamide containing at least one polymeric moiety according to formula (I) wherein each a is independently from each other selected from 1, 2 and 3; each b is an integer independently from each other ranging from 5 to 10000; each R1 is a monovalent residue independently from each other selected from the group consisting of substituted or unsubstituted C1-C8-alkyl groups and a method for its use are provided. Such etching solution is particularly useful for retaining the shape of treated copper and copper alloy lines.

Abstract: The present invention relates to novel processes for metallization of dielectric substrate surfaces applying organosilane compositions followed by oxidative treatment. The method results in metal plated surfaces exhibiting high adhesion between the substrate and the plated metal while at the same time leaves the smooth substrate surface intact.
