    摘要: An immersion liquid for immersion exposure process wherein a resist film is exposed through a liquid is disclosed. The immersion liquid is composed of a fluorine-containing liquid that is transparent to the exposure light used for the exposure process and has a boiling point of 70-270˚C. A resist pattern forming method which comprises a step wherein such an immersion liquid is directly placed on a resist film or a protective film is also disclosed. The immersion liquid prevents changes of properties in both of the resist film and the liquid during the immersion exposure process, thereby enabling to form a high-resolution resist pattern through immersion exposure.
