Abstract:
A substrate rinsing and drying method comprising the steps of:immersing a substrate, on which a resist film is formed, in water stored in a processing bath, thereby rinsing the substrate; feeding a hydrophobic liquid having a specific gravity greater than water into the processing bath from a bottom portion of the processing bath, thereby forming a first layer of the water and a second layer of the hydrophobic liquid with an interface being formed therebetween, the hydrophobic liquid being incapable of dissolving the resist film and substantially insoluble in water; further feeding the hydrophobic liquid into the processing bath from the bottom portion of the processing bath, thereby raising the interface so that the substrate passes through the interface and the substrate is entirely positioned in the second layer; further feeding the hydrophobic liquid into the processing bath from the bottom portion of the processing bath, thereby causing the water contained in the processing bank to overflow therefrom and driving out the water in the processing bath entirely; and removing the substrate from the hydrophobic liquid after driving out the water in the processing bath entirely, thereby allowing the substrate to be dried.
