Abstract:
1. A substrate support apparatus for seating and supporting a substrate during a process, the substrate support apparatus comprising: a movable stage provided with first drawing nozzles for attaching an area of a substrate to an upper surface of the movable stage and which is configured to rotate by a predetermined angle around a vertical axis so as to align the substrate using the one area of the substrate attached; a fixed stage spaced from the movable stage and provided with floating nozzles for ejecting air upward and floating the substrate while supporting another area of the substrate and second drawing nozzles for drawing air downward and fixing the aligned substrate; and a driver, coupled to the movable stage, which rotates the movable stage, wherein with the one area of the substrate attached and fixed to the movable stage and the another area of the substrate spaced from the fixed stage by a predetermined distance and floated, as the movable stage rotates, the another area of the substrate rotates and is aligned, and when the another area of the aligned substrate is attached and fixed to the fixed stage by the second drawing nozzles, the substrate is fixed.
