  • Patent number: 11905595
    Abstract: A film deposition apparatus includes a rotary table disposed in a vacuum chamber; multiple stages on each of which a substrate is placeable, the stages being arranged along a circumferential direction of the rotary table; a process area configured to supply a process gas toward an upper surface of the rotary table; a heat treatment area that is disposed apart from the process area in the circumferential direction of the rotary table and configured to heat-treat the substrate at a temperature higher than a temperature used in the process area; and a cooling area that is disposed apart from the heat treatment area in the circumferential direction of the rotary table and configured to cool the substrate.

  • Publication number: 20230096797
    Abstract: A gas management method includes: heating a raw material container that accommodates a raw material, by a heater, thereby generating a vaporized raw material gas; supplying the vaporized raw material gas together with a carrier gas to a processing container that accommodates a substrate, thereby performing a processing on the substrate; and controlling the heater based on a weight of the substrate after the processing on the substrate.

  • Publication number: 20230081958
    Abstract: A substrate processing method performed by a substrate processing apparatus including: a processing container that processes a substrate; a gas supply that supplies a gas into the processing container; an exhaust device that exhausts a gas from an inside of the processing container; and a gas analyzer that analyzes the gas passing through an exhaust pipe that connects the processing container and the exhaust device. The method includes: performing a processing with a processing gas in the processing container by supplying the processing gas into the processing container; purging the processing gas in the processing container by supplying a purge gas into the processing container; analyzing the processing gas passing through the exhaust pipe by the gas analyzer during the purging the processing gas; and determining a condition of the purging the processing gas based on a result of analyzing the processing gas.

  • Publication number: 20220223408
    Abstract: A method for depositing a silicon oxide film is provided. In the method, a silicon oxide film is deposited on a substrate by Atomic Layer Deposition with plasma while heating the substrate to a first temperature of 600° C. or higher. The silicon oxide film is annealed at a second temperature higher than the first temperature after completing the depositing the silicon oxide film.
