Abstract:
1. A contact assembly for use in an electrochemical deposition system to apply an electrical potential to a microelectronic workpiece, the contact assembly comprising: a support member having an inner wall defining an opening configured to allow the workpiece to move through the support member along an access path and a plurality of passageways configured to direct gas bubbles and/or electroplating solution through the contact assembly; and a contact system coupled to the support member, the contact system having at least one curved conductive mounting section attached to the support member and a plurality of contact members integral with the conductive mounting section projecting inwardly into the opening relative to the support member and transversely with respect to the access path, wherein the contact members each have a contact site configured to electrically contact the workpiece inwardly relative to the passageways.
