Patent number: 11948804Abstract: A substrate processing method includes preparing a phosphoric acid processing liquid, etching a substrate and increasing a concentration of the precipitation inhibitor. The phosphoric acid processing liquid is prepared by supplying a precipitation inhibitor into a phosphoric acid aqueous solution. The substrate having a silicon oxide film and a silicon nitride film is etched by immersing the substrate in a processing tub. The concentration of the precipitation inhibitor is increased by additionally supplying the precipitation inhibitor into the phosphoric acid processing liquid when a number of substrates etched has reached a first threshold value or when a silicon concentration in the phosphoric acid processing liquid has reached a second threshold value. The etching of the substrate comprises etching a new substrate by immersing the new substrate in the processing tub in which the phosphoric acid processing liquid with the increased concentration of the precipitation inhibitor is stored.Type: GrantFiled: February 24, 2022Date of Patent: April 2, 2024Assignee: TOKYO ELECTRON LIMITEDInventor: Takumi Honda
