Abstract: A method and apparatus for cleaning a wafer oriented vertically is provided. The apparatus includes a first brush and a second brush located horizontally from the first brush. During use, a wafer is orientated vertically between the first and second brushes. The brushes are brought into contact with the wafer and rotated thereby engaging the wafer with rollers. By rotating the rollers, the wafer is also rotated. Liquid is sprayed towards the brushes and wafer. By orienting the wafer vertically, liquid and particulates contained therein readily fall from the wafer due to gravity. This is particularly advantageous when cleaning larger diameter wafers in which particulates must be removed from a larger wafer surface area.

Abstract: In a spin dryer for semiconductor wafers, the wafer is held beneath a platen with its active side (i.e., the side containing the components or circuitry) facing upward. One or more nozzles spray rinse water on the top surface of the wafer and the wafer is rotated to remove the excess rinse water, thereby drying the wafer. A splash guard adjacent the edge of the wafer insures that the excess rinse water thrown off by the spinning wafer is deflected downward where it cannot again come into contact with the active side of the wafer. The platen is rotated dry at the same time, with no rinse water being splashed back onto the active side of the wafer. The spin dryer also includes a separate section which cleans and dries the end-effector of the robot which inserts the wafer into the spin dryer while the wafer is being dried.
