    • PURPOSE: A positive type photo-sensitive resin composition and a permanent resist obtained from the same are provided to improve pattern shapes although an optimal developing time for a developing process is passed. CONSTITUTION: A positive type photo-sensitive resin composition includes a polysiloxane compound with a carboxylic group and/or phenolic hydroxide group as a base resin, a photo-sensitive diazoquinone compound as a photo-sensitive component, and an organic solvent. The composition includes an epoxy siloxane compound in which groups represented by chemical formula 1 or a group represented by chemical formula 1 and a group represented by chemical formula 2 are connected by a residual group of a compound with 2 to 4 vinyl groups in one molecule except for vinyl groups. In chemical formula 1, R1 is identical or different and is a C1 to C4 alkyl group or a C6 to C10 aryl group; E is a group with an epoxy group; and a is 2 to 5. In chemical formula 2, b is 2 to 6 to satisfy inequality, 0
    • 目的:提供正型感光树脂组合物和由其获得的永久抗蚀剂,以改善图案形状,尽管通过显影过程的最佳显影时间。 构成:正型感光树脂组合物包括具有羧基和/或酚氢氧化物基团作为基础树脂的聚硅氧烷化合物,作为感光成分的光敏重氮醌化合物和有机溶剂。 该组合物包括环氧硅氧烷化合物,其中由化学式1表示的基团或由化学式1表示的基团和由化学式2表示的基团通过残留的一个具有2-4个乙烯基的化合物在一个分子中连接,除了 用于乙烯基。 在化学式1中,R 1相同或不同,为C 1〜C 4烷基或C 6〜C 10芳基; E是具有环氧基团的基团; 在化学式2中,b为2〜6,满足不等式,0
