摘要： An acid solution is fed onto a TiN film formed on a semiconductor substrate. So, the TiN film is dipped into the acid solution, whereupon the surface of the semiconductor substrate is neutralized or is made less basic. Then, a chemically amplified resist, containing an acid generator which produces an acid when irradiated with radiant rays and a compound reactive to acids, is applied to the semiconductor substrate, to form a resist film. This is followed by a step for sending radiant rays upon the resist film to expose it. Then, the exposed resist pattern is developed to form a resist pattern without footing or scumming and under-cutting.

摘要： After forming a lower layer film, an intermediate layer film and a first resist film on a substrate, a first resist pattern is formed by performing first exposure. Then, after a first intermediate layer pattern is formed by transferring the first resist pattern onto the intermediate layer film, a second resist film is formed thereon, and a second resist pattern is formed by performing second exposure. Thereafter, a second intermediate layer pattern is formed by transferring the second resist pattern onto the intermediate layer film. After removing the second resist film, the lower layer film is etched by using the second intermediate layer pattern as a mask, so as to form a lower layer pattern.

摘要： After forming a resist film made from a chemically amplified resist material pattern exposure is carried out by selectively irradiating the resist film with exposing light while supplying, onto the resist film, water that includes triphenylsulfonium nonaflate, that is, an acid generator, and is circulated and temporarily stored in a solution storage. After the pattern exposure, the resist film is subjected to post-exposure bake and is then 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.
