Patent ID: 8267103

Claim:
An apparatus for cleaning a substrate, comprising: a substrate support member including a rotatable chuck configured for receiving a substrate and rotating at a first speed; a first nozzle member configured for injecting a drying fluid onto a top surface of the substrate for drying the substrate and rotating at a second speed that is different than the first speed of the rotatable chuck; a low cover comprising a bottom surface, a side surface, and an opened top, the chuck being enclosed by the bottom surface and the side surface of the low cover; an upper cover movable with respect to the low cover for selectively covering the opened top and sealing against the side surface of the low cover; an isolated space disposed between the low cover and the upper cover for providing a closed space in which the substrate is treated, wherein the isolated space is sealed from the outside atmosphere and decompressed to a different pressure than a pressure of the outside atmosphere for drying of the substrate; and a control unit configured to control rotation of the rotatable chuck and the first nozzle member at different speeds at the same time; wherein the first nozzle member is installed to the upper cover.
