  • Patent number: 11521865
    Abstract: A substrate processing method includes a liquid discharging step of discharging liquid through a nozzle toward a predetermined supply region on the main surface of a substrate held on a substrate holding unit within a chamber, a humidified gas supplying step of supplying humidified gas with a humidity higher than the humidity within the chamber onto the main surface of the substrate to remove electrical charges carried on the substrate, and a spin-drying step of rotating the substrate about a predetermined rotational axis after the liquid discharging step to spin off the liquid component from the main surface of the substrate. The humidified gas supplying step is started before the start of the liquid discharging step and ended at a predetermined termination timing after the start of the liquid discharging step and before the spin-drying step.

  • 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: 10854481
    Abstract: A substrate processing method includes holding a substrate horizontally, supplying water-containing processing liquid to an upper surface of the substrate, forming a low surface tension liquid film, covering the upper surface by supplying that liquid to the substrate's upper surface, supplying a gas to a center region of the liquid film to form an opening in the center, widening the opening in order to remove the film, rotating the substrate around a predetermined rotational axis along a vertical direction, blowing, in the opening widening step, the gas toward a gas supply position that is set further inward than a peripheral edge of the opening on the upper surface of the substrate, and moving the gas supply position toward the peripheral edge of the upper surface of the substrate, and supplying, the low surface tension liquid toward a liquid landing position that is set further outward and moving the liquid landing position toward the peripheral edge of the upper surface of the substrate.
