Abstract:
A processing system for processing a substrate, comprising:a coating unit for coating the substrate with a coating solution; a solvent atmosphere unit for exposing the substrate to a solvent atmosphere of the coating solution; and a reduced-pressure drying unit for subjecting the substrate to reduced-pressure drying, wherein said coating unit comprises a coating solution discharge nozzle for discharging the coating solution onto the substrate, and a moving mechanism for relatively moving the coating solution discharge nozzle and the substrate, said solvent atmosphere unit comprises a chamber for holding the substrate in a prescribed atmosphere, and a solvent vapor supply mechanism for supplying a solvent vapor of the coating solution of a prescribed concentration into the chamber through a supply pipe, said reduced-pressure drying unit comprises a pressure reducing mechanism for reducing pressure inside a container in which the substrate is housed; the container is provided with an exhaust pipe for exhausting an atmosphere inside the container and a current plate for controlling a direction of airflow generated by exhaust from the exhaust pipe; a surface of the current plate facing the substrate is in parallel to the substrate; and the processing system further comprises a temperature adjusting unit for adjusting the temperature of the current plate.
