Abstract:
1. A liquid process apparatus comprising: a substrate holding unit configured to hold a substrate in a horizontal direction; a nozzle configured to supply a process liquid to the substrate held by the substrate holding unit; a cup located radially outside around the substrate when the substrate is held by the substrate holding unit, and configured to receive the process liquid supplied to the substrate by the nozzle; a top plate that moves in the horizontal direction between an advanced position, in which the top plate covers, from above, the substrate held by the substrate holding unit, and a retracted position, in which the top plate is retracted from the advanced position; and an air hood configured to supply a purified gas downward and move in the vertical direction between an air hood lower position, in which the air hood covers, from above, the substrate held by the substrate holding unit, and an air hood upper position located above the air hood lower position.
