Abstract:
A substrate processing system, comprising:a first rotary coating apparatus, disposed in a room, for coating a substrate with a first chemical supplied from above the substrate while rotating the substrate; a second rotary coating apparatus, disposed in the room, for coating the substrate with a second chemical supplied from above the substrate while rotating the substrate; atmospheric pressure measuring means for measuring the atmospheric pressure in the room; controlling means for controlling rotation speed at the time of coating in said first rotary coating apparatus based on an atmospheric pressure value measured by said atmospheric pressure measuring means; temperature and humidity measuring means for measuring the temperature and humidity in said second rotary coating apparatus; and controlling means for controlling rotation speed at the time of coating in said second rotary coating apparatus based on a temperature value and a humidity value measured by said temperature and humidity measuring means.
