【摘要】 本研究合成了甲基丙烯酸叔丁酯(TBMA)的均聚物及其与甲基丙烯酸(MAA)、苯乙烯(St)的共聚物,并与二乙烯基醚(BPA-DEVE)和光生酸剂(PAG)构成光敏成像体系。研究了两种不同光生酸剂和不同后烤版温度下体系的成像条件。研究表明:3,4-二甲氧基苯乙烯三嗪(DMOPV-TA)曝光产生的HCl对树脂中TBMA单元的酸解效果较差,但其对羧酸和BPA-DEVE形成的交联结构有较好的解交联效果;三苯胺硫鎓盐(TPASS)曝光产生的三氟甲磺酸对树脂中TBMA单元的酸解及体系解交联都有较好效果;同时,后烤版温度为140℃时成像感度高;在一定范围内,共聚树脂中MAA含量增加,体系的成像感度也增加。更多还原

【Abstract】 In this study, a homopolymer and a series of copolymer of tert-butyl methacrylate(TBMA) with Methacrylic Acid (MAA) and styrene (St) were sysnthsized. And these copolymer were used to make a photosensitive imaging system with bisvinyl ether(BPA-DEVE) and photochemical acid generator(PAG). The imaging factors of two different PAGs and different postbaking temperatures were investigated. The experiments results indicated that 2-(3,4-dimethoxyphenyl)vinyl triazine had a poor acid effect on TBMA unit in coplymers and a better decrosslinking effecct on crosslinking of carboxylic acid and BPA-DEVE. While triphenylamine sulfonium salt had a better effect on both. And imaging sensitivety was high when postbaking temperature was at 140℃ and in some range the more content of MAA in complylers result in higher imaging sensitivety.更多还原
