  • Patent number: 7861731
    Abstract: A cleaning/drying apparatus including a vapor area where vapor of an organic solvent inside the cleaning/drying apparatus is generated, an ejecting part configured to eject the organic solvent onto a cleaning/drying target, a first detecting part configured to determine whether the temperature of the cleaning/drying target is a first temperature equivalent to a temperature of the vapor in the vapor area, a second detecting part configured to determine whether the temperature of the cleaning/drying target is a second temperature enabling the organic solvent to condense on a surface of the cleaning/drying target, and a cleaning/drying control part configured to drive the ejecting part to eject the organic solvent when the first detecting part detects that the temperature of the cleaning/drying target is the first temperature and stop the ejection when the second detecting part detects that the temperature of the cleaning/drying target is the second temperature.
