Abstract
The present invention relates to a method for performing coating and developing treatment for a substrate, which comprises the steps of: supplying a coating solution to the substrate to form a coating film on the substrate; performing heat treatment for the substrate on which the coating film is formed; cooling the substrate after the heat treatment; performing exposure processing for the coating film formed on the substrate; and developing the substrate after the exposure processing, and further comprises the step of supplying a treatment gas to form a treatment film on a surface of the coating film after the step of forming the coating film and before the step of performing the exposure processing for the substrate. According to the present invention, the treatment gas is supplied to form the treatment film on the surface of the coating film after the step of forming: the coating film and before the step of exposing the substrate, whereby the substrate can be protected from impurities such as oxygen and water vapor in an atmosphere by this treatment film.
