  • Patent number: 10636682
    Abstract: In a substrate processing apparatus, the inner peripheral edge of a second-cup canopy part radially opposes an outer peripheral surface of an opposing-member side wall part. This suppresses dispersion of processing liquids to above a cup part. A second-cup gap distance that is a radial distance between the outer peripheral surface of the opposing-member side wall part and the inner peripheral edge of the second-cup canopy part is greater than a holder gap distance that is a radial distance between the inner peripheral surface of the opposing-member side wall part and the outer peripheral surface of the substrate holder. This prevents or suppresses the possibility that, when a second processing liquid dispersed from a substrate is received by a second cup, the second processing liquid may be pushed downward by a downward airflow. Accordingly, a plurality of types of processing liquids will be separately received by a plurality of cups.
