  • Publication number: 20070232073
    Abstract: After a liquid chemical treatment is finished, in parallel with a washing away treatment and/or a drying treatment, by spraying from a nozzle for a cleaning liquid supplied by a cleaning line to an outer surface of a nozzle for a liquid chemical, crystals and the like of components of the liquid chemical adhered on the outer surface of the nozzle are removed. In the cleaning treatment, a spraying time of the cleaning liquid is five seconds to ten seconds. In addition, the components of the cleaning liquid is not specifically limited, however, since ammonium phosphate tends to be solved in purified water, if a liquid chemical containing ammonium phosphate is used, it is preferable to use purified water as the cleaning liquid. Depending on the components and the like of the liquid chemical, a solution that can solve the crystals and the like may be used in stead.
