Publication number: 20230017418Abstract: An upper holding device holds a substrate in a horizontal attitude without rotating the substrate. A lower holding device rotates a substrate while holding the substrate by suction. A substrate held by the upper holding device is cleaned with use of a cleaning liquid, and a substrate held by the lower holding device is cleaned with use of a cleaning liquid. Gas in a processing space is exhausted by exhaust equipment of a factory through an exhaust system. When a substrate is held by the upper holding device, gas in the processing space is not exhausted or gas in the processing space is exhausted at a first flow rate. Gas in the processing space is exhausted at a second or third flow rate that is higher than the first flow rate when the substrate is held by the lower holding device.Type: ApplicationFiled: July 14, 2022Publication date: January 19, 2023Inventors: Nobuaki OKITA, Junichi ISHII, Kazuki NAKAMURA, Takashi SHINOHARA, Yoshifumi OKADA, Tomoyuki SHINOHARA, Takuma TAKAHASHI
