Abstract:
A method and apparatus is disclosed for reclaiming a metal from the effluent of a chemical mechanical planarization (CMP) process and using the reclaimed metal in an electroplating process. The steps of the method include using a chemical solution in a (CMP) process to remove material from a semiconductor device. An effluent is produced by this step that contains a dissolved first species removed from the semiconductor device. Then a second step of treating the effluent is performed to remove the dissolved first species and to produce a reclaimed metal. Then a third step of using the metal in an electroplating process is performed.
