Zusammenfassung:	In one example, an electroplating apparatus is provided for electroplating a wafer. The electroplating apparatus comprises a wafer holder for holding a wafer during an electroplating operation and a plating cell configured to contain an electrolyte during the electroplating operation. An anode chamber is disposed within the plating cell, and a charge plate is disposed within the anode chamber. An anode is positioned above the charge plate within the anode chamber. In some examples, the anode chamber is a membrane-less anode chamber.
