Abstract:
An improved method of stabilizing wet chemical baths is disclosed. Typically such baths are used in processes for treating workpieces, for example, plating processes for plating metal onto substrates. In particular, the present invention relates to copper plating baths. More particularly, the present invention relates to the stability of copper plating baths. More particularly, the present invention relates to prevention of void formation by monitoring the accumulation of deleterious by-products in copper plating baths.
