  • Publication number: 20210304032
    Abstract: A learned model generating method includes: acquiring learning data; and generating a learned model for estimating a factor of an abnormality of a processing target substrate after processing using a processing fluid by performing machine learning of the learning data. The learning data includes a feature quantity and abnormality factor information. The abnormality factor information represents a factor of an abnormality of a learning target substrate after processing using the processing fluid. The feature quantity includes first feature quantity information representing a feature of a time transition of section data in time series data representing a physical quantity of an object used by a substrate processing device that processes the learning target substrate using the processing fluid. The first feature quantity information is represented using times.

  • Patent number: 9984903
    Abstract: A treatment cup cleaning method is provided, which includes: a rotating step of rotating a substrate rotating unit with a substrate being held by the substrate rotating unit; a cleaning liquid supplying step of supplying a cleaning liquid to an upper surface and a lower surface of the substrate and causing the cleaning liquid to scatter from a peripheral edge of the substrate to be applied to an inner wall of a treatment cup in the rotating step, whereby the cleaning liquid is supplied to the inner wall of the treatment cup; and a scattering direction changing step of changing a cleaning liquid scattering direction in which the cleaning liquid scatters from the peripheral edge of the substrate in the rotating step and the cleaning liquid supplying step.
