Patent number: 11869780Abstract: A substrate liquid processing apparatus includes a processing liquid storage unit configured to store a processing liquid therein; a processing liquid drain unit configured to drain the processing liquid from the processing liquid storage unit; and a control unit. The control unit performs a first control in a constant concentration mode in which a concentration of the processing liquid in the processing liquid storage unit is regulated to a predetermined set concentration and a second control in a concentration changing mode in which the concentration of the processing liquid is changed. In the second control, a set concentration after concentration change is compared with a set concentration before the concentration change, and when the set concentration after the concentration change is lower, the control unit controls the processing liquid drain unit to start draining of the processing liquid.Type: GrantFiled: September 10, 2018Date of Patent: January 9, 2024Assignee: TOKYO ELECTRON LIMITEDInventors: Takahiro Kawazu, Takafumi Tsuchiya, Hideaki Sato, Hidemasa Aratake, Osamu Kuroda, Takashi Nagai, Jiro Harada

Patent number: 11745213Abstract: A substrate processing apparatus includes a processing tub, a liquid recovery unit, a liquid recovery unit drain line, a storage, a first and a second liquid supply lines, a discharge line, a first and a second liquid flow rate controllers. The liquid recovery unit receives a processing liquid overflown from the processing tub. The liquid recovery unit drain line drains the processing liquid from the liquid recovery unit. The first and the second liquid supply lines supply a first and a second liquids, respectively. The cleaning liquid contains the first liquid and the second liquid, and removes a precipitate from the processing liquid. The discharge line discharges the cleaning liquid, the first liquid or the second liquid toward the liquid recovery unit. The first and the second liquid flow rate controllers are provided at the first and the second liquid supply lines, and adjust flow rates thereof, respectively.Type: GrantFiled: October 13, 2020Date of Patent: September 5, 2023Assignee: TOKYO ELECTRON LIMITEDInventors: Hidemasa Aratake, Osamu Kuroda, Kouzou Kanagawa
