| description | PROBLEM TO BE SOLVED: To prevent the lowering of the treatment rate and non-uniformity of a chemical liquid supplied to the surface of a substrate caused by the lowering of temperature, in the treatment of the substrate for supplying the chemical liquid to the surface of the substrate while rotating the substrate by a rotor. SOLUTION: A cooling fan 30 for forming a down flow in a treatment tank 20 is constituted in a speed changeable manner and an on-off damper 73 is provided to an exhaust system 70 for evacuating the treatment tank 20. When treating with the chemical liquid, the on-off damper 73 is closed and the cooling fan 30 is rotated at a low speed so as to make suction quantity slightly larger than exhaustion quantity. |
