Patent number: 12042815Abstract: A substrate processing apparatus includes a processing tank, a holder, an organic solvent supply, a drainage port, a gas supply, and an exhaust port. The processing tank stores an aqueous layer. The holder holds a substrate. The organic solvent supply supplies an organic solvent onto the aqueous layer to form a liquid layer of the organic solvent. The drainage port discharges the aqueous layer from a bottom wall of the processing tank and causes the liquid layer of the organic solvent to descend from above the substrate to below the substrate. The gas supply supplies a gas of a water repellent agent to the liquid layer from above the processing tank while the liquid layer descends. The exhaust port is exposed on a side wall of the processing tank by the descending of the liquid layer and discharges the gas of the water repellent gas.Type: GrantFiled: September 29, 2021Date of Patent: July 23, 2024Assignee: TOKYO ELECTRON LIMITEDInventors: Kotaro Tsurusaki, Koji Yamashita, Yusuke Yamamoto, Koji Tanaka, Kouzou Kanagawa

Publication number: 20170032983Abstract: A thermal catalytic layer is formed on the inner surface of a processing container and heated. Thus, when a sublimate sublimated from a coating film on a wafer W and received within the processing container reaches the vicinity of the thermal catalytic layer, the sublimate is decomposed and removed by the thermal activation of the thermal catalytic layer. In removing a sublimate attached to a light transmission window, a cleaning substrate formed with the thermal catalytic layer on the surface thereof is carried into the processing container and caused to approach the light transmission window. Thereafter, the cleaning substrate is heated so that the sublimate attached to the surface of the light transmission window is removed.Type: ApplicationFiled: July 27, 2016Publication date: February 2, 2017Inventors: Koshi MUTA, Tsuyoshi MORIYA, Takuya MORI, Kazuhiro TAKESHITA, Tomonori ESAKI, Kouichi MIZUNAGA, Masataka TANAKA, Kouzou KANAGAWA, Keigo NAKANO
