Abstract:
A wafer processing apparatus having a sealable internal process chamber within which a wafer can be supported at multiple positions, said apparatus comprising:a support;a process chamber operatively connected with said support and comprising a rinse bowl member that provides a chamber bottom, a top cover member that provides a chamber top and a wall between the rinse bowl portion and the top cover member that surrounds an internal process chamber, the wall also including a wafer transfer opening to permit a wafer to be selectively loaded into and removed from the internal process chamber, and the rinse bowl member having an access opening;a wafer support chuck rotatably supported within the internal process chamber, the support chuck also being operatively connected with a first rotatable drive device and being displaceable in a first direction, the support chuck thus being positionable within the internal process chamber in multiple positions between the top cover member and the rinse bowl member of the process chamber;a first motion drive device that is operatively connected to the support and which is further operatively connected with the wafer support chuck to move the wafer support chuck between multiple different positions within the internal process chamber.
