Abstract:
A substrate processing apparatus, comprising:a coating processing unit for applying a resist solution to a substrate;a developing processing unit for performing developing processing for the substrate after the applied resist film is exposed;a cooling section for cooling outside air taken in from the outside to a predetermined temperature;a heat exchanger having a low temperature side flow path for letting the air cooled in said cooling section flow and a high temperature side flow path for letting outside air flow, and allowing heat exchange to be performed between the cooled air and the outside air;a warming and humidifying section for warming and humidifying the air flowing through the low temperature side flow path in said heat exchanger and warmed by the outside air flowing through the high temperature side flow path, and supplying the air with predetermined temperature and humidity to said coating processing unit; anda warming section for warming the outside air flowing through the high temperature side flow path in said heat exchanger and cooled by the air flowing through the low temperature side flow path, and supplying the air with a predetermined temperature to said developing processing unit.
