A multi-chambered system for electroplating metal layers on a semiconductor substrate. The system comprises a fluid reservoir having at least a first chamber and a second chamber. A cathode is located in the first chamber, an anode is located in the second chamber, and a shield is located between the cathode and anode. The cathode is configured to be electrically coupled to a semiconductor substrate locatable in the first chamber. The anode is configured to oppose a first major surface of the semiconductor substrate. The shield is configured to deter electrolytic fluid communication between the first and second chamber, other than through predefined openings in the shield.
