    • A thermoacid generator for antireflective film formation, characterized by being represented by the following formula (1): (wherein R1 represents C1-20 alkyl, alkenyl, oxoalkyl, or oxoalkenyl (hydrogen atoms in these groups may have been replaced with fluorine atoms); R2 represents linear, branched, or cyclic C1-20 alkyl, alkenyl, oxoalkyl, or oxoalkenyl, C6-20 aryl, or C7-12 aralkyl or aryloxoalkyl; R3 represents hydrogen or alkyl; and Y− represents a non-nucleophilic counter ion); a composition for forming an antireflective film; and an antireflective film made from the composition. With the thermoacid generator and composition, satisfactory etching resistance and the satisfactory ability to prevent the reflection of short-wavelength light (ability to absorb short-wavelength light) are attained. Furthermore, the antireflective film can inhibit an overlying photoresist film from generating a scum.
    • 用于抗反射膜形成的热酸发生器,其特征在于由下式(1)表示:(其中R 1表示C 1-20烷基,烯基,氧代烷基或氧代烯基(这些基团中的氢原子可被氟原子取代); R 2表示直链,支链或环状C 1-20烷基,烯基,氧代烷基或氧代烯基,C 6-20芳基或C 7-12芳烷基或芳氧基烷基; R 3表示氢或烷基; Y-表示非亲核抗衡离子) ; 用于形成抗反射膜的组合物; 和由该组合物制成的抗反射膜。 利用热酸发生器和组合物,可获得令人满意的耐蚀刻性和令人满意的防止短波长光反射(能够吸收短波长光)的能力。 此外,抗反射膜可以抑制上覆的光致抗蚀剂膜产生浮渣。
