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.
A method of depositing a conductive material on a workpiece and cleaning the workpiece in a chamber, the method comprising the steps of:
