    Abstract: A substrate processing apparatus includes a chamber, a substrate support positioned inside the chamber and supporting a substrate, an edge frame disposed above the substrate support and extending outward from an edge of the substrate support, and a gas flow-controlling unit installed on a side wall of the chamber to be positioned between the side wall of the chamber and a side surface of the substrate support along a periphery of the substrate support. The gas flow-controlling unit includes a flow path provided in a region overlapping the edge frame. Thus, the gas may be prevented from flowing unevenly to the corners or regions other than the corners within the chamber. That is, the gas may be evenly distributed in the circumferential direction of the chamber. Accordingly, the cleaning defect may be prevented from occurring at the corners of the chamber and in regions other than the corners.
