Abstract
A substrate processing method which includes an exposure step wherein an immersion area of a first liquid is formed on a substrate and the substrate is exposed by being irradiated with an exposure light through the first liquid, and an immersion step wherein the substrate is immersed in a second liquid before the exposure step. By this method, occurrences of problems caused by adhesion marks, which are always involved in immersion exposure, can be reduced.
