摘要： Conventional detergents for lithography which contain a surfactant as an active ingredient should have a reduced surfactant concentration because heightened surfactant concentrations result in dissolution of the resin component of a photoresist composition and hence in a dimensional change of a resist pattern. However, the conventional detergents have had a drawback that such a low concentration unavoidably reduces the ability to inhibit pattern falling and defect occurrence. A detergent for lithography is provided which is an aqueous solution containing (A) at least one member selected among nitrogenous cationic surfactants and nitrogenous ampholytic surfactants and (B) an anionic surfactant. This detergent retains a low surface tension even when it has a low concentration. It is effective in inhibiting pattern falling and defect occurrence. It can also inhibit resist patterns from fluctuating in dimension.

摘要： A method of producing a high-quality product without damaging the physical properties of a pattern to be formed by a rinsing process based on a principle totally different from that for a conventional pattern collapse preventing method. A method for forming a resist pattern by subjecting a photo-resist layer provided on a substrate to image-forming exposure and then developing the resultant layer, wherein the resist pattern is formed, after the developing process, by the process of reducing a contact angle with respect to a contact liquid on the surface of the resist pattern to up to 40 degrees, then by the process of increasing it to at least 70 degrees, and further by drying it.
