Current-leveling electroplating/electropolishing electrode |
摘要 |
A current-leveling electrode for improving electroplating and electrochemical polishing uniformity in the electrochemical plating or electropolishing of metals on a substrate is disclosed. The current-leveling electrode includes a base electrode and at least one sub-electrode carried by the base electrode. The at least one sub-electrode has a width which is less than a width of the base electrode to impart a generally tapered, stepped or convex configuration to the current-leveling electrode.
