Abstract: Substantially uniform deposition of conductive material on a surface of a substrate, which substrate includes a semiconductor wafer, from an electrolyte containing the conductive material can be provided by way of a particular device which includes first and second conductive elements. The first conductive element can have multiple electrical contacts, of identical or different configurations, or may be in the form of a conductive pad, and can contact or otherwise electrically interconnect with the substrate surface over substantially all of the substrate surface. Upon application of a potential between the first and second conductive elements while the electrolyte makes physical contact with the substrate surface and the second conductive element, the conductive material is deposited on the substrate surface. It is possible to reverse the polarity of the voltage applied between the anode and the cathode so that electro-etching of deposited conductive material can be performed.

Abstract: The present invention relates to a containment chamber that is used for carrying out multiple processing steps such as depositing on, polishing, etching, modifying, rinsing, cleaning, and drying a surface on the workpiece. In one example of the present invention, the chamber is used to electro chemically mechanically deposit a conductive material on a semiconductor wafer. The same containment chamber can then be used to rinse and clean the same wafer. As a result, the present invention eliminates the need for separate processing stations for depositing the conductive material and cleaning the wafer. Thus, with the present invention, costs and physical space are reduced while providing an efficient apparatus and method for carrying out multiple processes on the wafer surface using a containment chamber.

Abstract: A particular anode assembly can be used to supply a solution for any of a plating operation, a planarization operation, and a plating and planarization operation to be performed on a semiconductor wafer. The anode assembly includes a rotatable shaft disposed within a chamber in which the operation is performed, an anode housing connected to the shaft, and a porous pad support plate attached to the anode housing. The support plate has a top surface adapted to support a pad which is to face the wafer, and, together with the anode housing, defines an anode cavity. A consumable anode may be provided in the anode cavity to provide plating material to the solution. A solution delivery structure by which the solution can be delivered to said anode cavity is also provided. The solution delivery structure may be contained within the chamber in which the operation is performed. A shield can also be mounted between the shaft and an associated spindle to prevent leakage of the solution from the chamber.

Abstract: Deposition of conductive material on or removal of conductive material from a workpiece frontal side of a semiconductor workpiece is performed by providing an anode having an anode area which is to face the workpiece frontal side, and electrically connecting the workpiece frontal side with at least one electrical contact, outside of the anode area, by pushing the electrical contact and the workpiece frontal side into proximity with each other. A potential is applied between the anode and the electrical contact, and the workpiece is moved with respect to the anode and the electrical contact. Full-face electroplating or electropolishing over the workpiece frontal side surface, in its entirety, is thus permitted.
