Abstract
Removing metal from a semiconductor substrate by dissolving ions of the metal into an electrolyte, comprising the steps of: applying a voltage across a polishing pad and the substrate, while an electropolishing electrolyte is dispensed at an interface of the substrate and the polishing pad, and while pooling the electrolyte about the substrate by the polishing pad.
