An integrated tool is provided including at least one workpiece processing
station having a paddle assembly. In accordance with another independent
aspect of the present invention, the workpiece processing station is
adapted for adjusting the level of the processing fluid relative to a
workpiece, wherein the portion of the workpiece to be processed and
possibly the paddle is selectively immersed within the processing fluid.
In accordance with a further independent aspect of the present invention,
a paddle is provided for use proximate to a workpiece in a workpiece
processing station. The paddle includes a one or more sets of delivery
ports and one or more sets of fluid recovery ports. In at least one
embodiment, the paddle provides for agitation of a processing fluid
proximate to the surface of the workpiece. In at least another
embodiment, the paddle provides for the delivery and/or recovery of one
or more fluids to the portion of the workpiece to be processed. One
aspect of the present invention enables the fluids supplied to the
workpiece by the paddle to be limited to the space located between the
workpiece and the paddle, thus avoiding mixing of these fluids with the
processing fluid located within the bowl assembly not supplied by the
paddle.
