    摘要: The disclosed embodiments relate to methods and apparatus for immersing a substrate in electrolyte in an electroplating cell under sub-atmospheric conditions to reduce or eliminate the formation/trapping of bubbles as the substrate is immersed. Various electrolyte recirculation loops are disclosed to provide electrolyte to the plating cell. The recirculation loops may include pumps, degassers, sensors, valves, etc. The disclosed embodiments allow a substrate to be immersed quickly, greatly reducing the issues related to bubble formation and uneven plating times during electroplating.

    摘要: Apparatus and methods for electroplating are described. Apparatus described herein include anode supports including positioning mechanisms that maintain a consistent distance between the surface of the wafer and the surface of a consumable anode during plating. Greater uniformity control is achieved. The consumable anode in one implementation has a plurality of through channels and at least one depression on its surface (e.g., a depression surrounding a channel) that is configured for registering with a protrusion on a component of an anode assembly, such as with a support plate. Fasteners may pass through the channels in the anode and attach it to a charge plate.
