Electroless copper plating is widely used for the fabrication of printed circuit boards and other electronic devices. Electroless copper can provide a seed layer on a dielectric material for subsequent acid copper electroplating. 5 There is renewed interest in copper deposition for ultra-large scale integrated circuits (ULSI) because of the higher conductivity of copper versus aluminum.
