Stable electroless copper plating compositions and methods for electroless plating copper on substrates

A specific cysteine derivative is added to electroless copper plating compositions to improve the stability of the electroless copper plating compositions such that the plating activity of the electroless plating copper compositions is not compromised even when electroless plating at low plating tem...

Zusammenfassung:A specific cysteine derivative is added to electroless copper plating compositions to improve the stability of the electroless copper plating compositions such that the plating activity of the electroless plating copper compositions is not compromised even when electroless plating at low plating temperatures and high stabilizer and high leached catalyst concentrations.
