Patent number: 9301397Abstract: Metalized web substrate is wet etched in a reaction vessel by contacting with oxidizing and metal complexing agent to remove metal from unpatterned region. Following etching, substrate is rinsed, and rinse is at least partly recycled. Concentrations of oxidizing and metal complexing agents in the etchant bath are maintained by delivering replenishment feeds of each. Concentration of metal in the etchant bath is maintained by discharging some of the etchant bath. Replenishment rates of oxidizing and metal complexing agents and etchant removal rate are determined based at least in part on rate that metal etched from the substrate enters the etchant bath.Type: GrantFiled: September 19, 2012Date of Patent: March 29, 2016Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Jeffrey H. Tokie, Joseph W. Woody, V, Thomas M. Lynch, Daniel M. Lentz, Robert S. Davidson, Cristin E. Moran, Lijun Zu
