Abstract

A new method is described for initiating electroless copper deposition onto dielectric substrates. The method employs a thin poly(acrylic acid) film, applied to the substrate by dip-coating, to bind Pd+2 from PdSO4 solution. Uptake of Pd+2 takes place by H+/Pd+2 ion exchange at the carboxylic acid sites of the polymer. Upon immersion of a substrate treated with Pd+2/poly(acrylic acid) into an electroless copper plating bath, reduction of Pd+2 to Pd0 takes place, forming an active catalyst for the initiation of electroless copper plating.
