A process and composition for use in electroless copper plating where the process includes contacting a substrate with a solution comprising copper, a complexing agent, a reducing agent, and a pH adjuster. A stabilizer may also be used. The improvement of the present invention includes contacting the substrate with a solution further comprising ammonium ions present in an amount effective to function as a plating rate controller. The improved solution is relatively stable, easy to control, and is of versatile use. |
