ABSTRACT:
An apparatus for drying a generally flat substrate that has been cleaned has a rotatable support for supporting the substrate, a substrate drying assembly, and a controller. The substrate drying assembly includes a substrate drying assembly support arm, an outlet for applying liquid to an upper surface of the substrate, and an outlet for applying a drying vapor to the upper surface of the substrate. The substrate drying assembly is configured to position the liquid applying outlet and to position the vapor applying outlet above a portion of the substrate. The controller causes the substrate drying assembly to be retracted over the upper surface of the substrate at a faster rate near a center of the substrate than near a periphery of the substrate.
