    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: Provided are: a resist surface modifying liquid which is used as a surface treatment liquid of a resist film prior to a post exposure baking (PEB) step, and which can inhibit occurrence of defects of the resist film by reducing water repellency; and a method for forming a resist pattern using the same. A resist surface modifying liquid which is used as a surface treatment liquid prior to a post exposure baking (PEB) step of a resist film, the resist surface modifying liquid containing an acidic compound, and at least one of an alcohol-based solvent represented by a certain general formula and an ether-based solvent represented by a certain general formula.
