Abstract
CMOS processing is enhanced via a method and system that use a chemical bath purification process. According to an example embodiment of the present invention, solution from a CMOS wet chemical bath is passed over a powered circuit. The powered circuit plates out copper from the solution, and the solution is then returned to the bath. By removing copper from the chemical bath in this manner, cross-contamination of wet chemical equipment is reduced, and the need for redundant tool sets can be eliminated.
