  • Patent number: 8512478
    Abstract: A cleaning and drying-preventing method including: positioning a nozzle in a container such that a funnel-like inner circumferential surface of the container is located around a periphery of a distal end of the nozzle; sucking a liquid in the nozzle to retract a level of the liquid to a side of a supply passage; supplying a solvent into the container to form a swirl flow of the solvent turning around the distal end of the nozzle, and cleaning the nozzle by the swirl flow; supplying a solvent into the container to form a liquid pool of the solvent; and further retracting the level of the liquid in the nozzle to the side of the supply passage. A liquid layer, an air layer, and a solvent layer are formed in the nozzle in this order from the side of the supply passage, to prevent drying of the liquid in the nozzle.

  • Patent number: 7901514
    Abstract: A cleaning method of cleaning a surface of a substrate that is processed by a developing process. The method includes pouring a cleaning liquid onto a central part of the substrate. A dry area that is not wetted with the cleaning liquid is created in a central part of the substrate by stopping pouring the cleaning liquid or by shifting a cleaning liquid pouring position to which the cleaning liquid is poured from the central part while the substrate holding device is rotating. The dry area is expanded outward from the central part of the substrate by rotating the substrate holding device at a rotating speed not lower than 1500 rpm without pouring the cleaning liquid onto the dry area. The cleaning liquid is poured onto an outer area contiguously surrounding the dry area on the surface of the substrate.

  • Patent number: 7604013
    Abstract: A cleaning method highly effectively cleans a surface of a semiconductor wafer by removing a dissolution product, produced when a surface of a semiconductor wafer is processed by a developing process that develops an exposed film formed on the semiconductor wafer by wetting the exposed film with a developer, from the surface of the semiconductor wafer. A cleaning liquid is poured through a cleaning liquid pouring nozzle onto a central part of a rotating wafer processed by a developing process to spread the cleaning liquid in a film over the surface of the wafer. Then, the cleaning liquid pouring nozzle is shifted to create a dry area in a central part of the wafer and the wafer is rotated at 1500 rpm to expand the dry area.
