ABSTRACT:
A metal is deposited onto a substrate from an electroless plating solution by plating an initial layer of metal onto the substrate, then contacting the metal-plated substrate with a solution of an acid; and plating an additional layer of metal onto the plated, acid-treated substrate. The process reduces the plating void defects.
