After forming a resist film made from a chemically amplified resist material, pattern exposure is carried out by irradiating the resist film with exposing light while supplying, between a projection lens and the resist film, a solution of water (having a refractive index of 1.44) that includes an antifoaming agent and is circulated and temporarily stored in a solution storage. After the pattern exposure, the resist film is subjected to post-exposure bake, and the resultant resist film is developed with an alkaline developer. Thus, a resist pattern made of an unexposed portion of the resist film can be formed in a good shape.
