发明名称 Resist pattern forming method, semiconductor apparatus using said method, and exposure apparatus thereof
摘要 In immersion exposure, a resist pattern forming method suppressing resist pattern defects comprises mounting a substrate formed a resist film thereon and a reticle formed a pattern thereon onto an exposure apparatus, supplying a first chemical solution onto the resist film to selectively form a first liquid film in a local area on the resist film and draining the solution, the first liquid film having a flow and being formed between the resist film and a projection optical system, transferring the pattern of the reticle to the resist film through the first liquid film to form a latent image, supplying a second chemical solution onto the resist film to clean the resist film, heating the resist film, and developing the resist film to form a resist pattern from the resist film.
