Patent ID: 7138016

Claim:
An apparatus for processing a single wafer, such as a semiconductor wafer, a magnetic disk, or an optical disk, comprising: a framework; a processing bowl mounted to the framework, the processing bowl comprising an inner portion having an interior adapted to receive a pool of a processing chemical, an outer portion, and a fluid-receiving space between the inner portion and the outer portion; a chemical supply adapted to supply the processing chemical to the processing bowl; a processor head mounted for movement between at least one loading position and at least one processing position, the processor head in its loading position being adapted to position a wafer outside the interior of the inner portion, the processor head carrying a rotatable wafer support adapted to support a wafer within the interior of the inner portion when the processor head is in the processing position, wherein a portion of the head extends radially outward over and along an upper edge of the bowl; a second processing chamber; and a wafer transfer adapted to move wafers to and from the processing bowl, and to and from the second processing chamber.
