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.

Disclosed in an adhesive film which enables to obtain a flexible metal clad laminate which is suppressed in dimensional change when produced by heat roll lamination. Such an adhesive film comprises a heat-resistant layer containing a highly heat resistant polyimide and an adhesive layer which is formed on at least one surface of the heat-resistant layer and contains a thermoplastic polyimide. In this adhesive film, the thermal shrinkage ratio in the TD direction is not less than +0.01%, and the thermal shrinkage ratio in the MD direction is not more than −0.02%. Consequently, when a metal layer and the adhesive film are bonded together by heat roll lamination and the resulting laminate is subjected to a treatment with heating, occurrence of dimensional changes can be sufficiently suppressed.
