A silicon-containing film is formed from a heat curable composition comprising (A) a silicon-containing compound obtained through hydrolytic condensation of a hydrolyzable silicon compound in the presence of an acid catalyst, (B) a hydroxide or organic acid salt of Li, Na, K, Rb or Ce, or a sulfonium, iodonium or ammonium compound, (C) an organic acid, (D) a cyclic ether-substituted alcohol, and (E) an organic solvent. The silicon-containing film ensures effective pattern formation, effective transfer of a photoresist pattern, and accurate processing of a substrate.
含硅薄膜由一种热固化组合物形成,该组合物包括:(A) 在酸催化剂存在下通过可水解硅化合物的水解缩合得到的含硅化合物;(B) Li、Na、K、Rb 或 Ce 的氢氧化物或有机酸盐,或锍、碘或铵化合物;(C) 有机酸;(D) 环醚取代醇,以及 (E) 有机溶剂。 含硅薄膜可确保图案的有效形成、光刻胶图案的有效转移以及基底的精确加工。
