摘要: A positive type photoresist composition contains (a) 100 parts by weight of a resin which is a polymer compound (A) including carbon-carbon double bonds and having a molecular weight of 300 to 30,000 and an iodine value of 50 to 500. To at least a part of the double bonds of the polymer compound (A), a group represented by the formula (I) is introduced
wherein R¹ denotes a hydrogen atom, a halogen atom or an alkyl group having 1 to 3 carbon atoms and R² denotes an alkyl group having 1 to 10 carbon atoms, a cycloalkyl group or an aryl group. The composition further contains (b) 25 to 100 parts by weight of a compound containing a quinone diazide unit.摘要翻译: 正型光致抗蚀剂组合物含有(a)100重量份作为包含碳 - 碳双键并且分子量为300〜30,000,碘值为50〜500的高分子化合物(A)的树脂。 引入高分子化合物(A)的双键的至少一部分,由式(I)表示的基团
,其中R 1表示氢原子,卤素原子或具有1〜3个碳原子的烷基 碳原子,R 2表示碳原子数1〜10的烷基,环烷基或芳基。 该组合物还含有(b)25〜100重量份的含有醌二叠氮单元的化合物。
