Description
技术领域
本发明涉及光刻胶树脂单体领域,尤其涉及光敏型树脂单体及其合成方法。
背景技术
光刻技术是指利用光刻材料(特指光刻胶)在可见光、紫外线、电子束等作用下的化学敏感性,通过曝光、显影、刻蚀等工艺过程,将设计在掩膜版上的图形转移到衬底上的图形微细加工技术。
光刻材料(特指光刻胶),又称光致抗蚀剂,是光刻技术中涉及的最关键的功能性化学材料,主要成分是树脂、光酸产生剂、以及相应的添加剂和溶剂,这类材料具有光(包括可见光、紫外线、电子束等)化学敏感性,经光化学反应,本身在显影液中的溶解性发生变化。根据光化学反应机理不同,光刻胶分为正性光刻胶与负性光刻胶:曝光后,光刻胶在显影液中溶解性增加,得到与掩膜版相同图形的称为正性光刻胶;曝光后,光刻胶在显影液中溶解性降低甚至不溶,得到与掩膜版相反图形的称为负性光刻胶。
光敏树脂单体是光刻胶聚合树脂的重要组成部分,主要作用是曝光前后产生极性差,从而导致在极性显影剂中溶解度不同,本发明提供一种新型结构的光敏型光刻胶树脂单体。

d.中间体D在碱性条件下与卤代物F反应生成树脂单体E。
作为本发明的一种优选技术方案,合成步骤a的氧化剂为间氯过氧苯甲酸或者过氧化氢。

与现有技术相比,本发明的有益效果如下:
本发明提供了一种新的光刻胶树脂单体,树脂单体含有光敏基团,与其它树脂单体聚合形成光刻胶树脂聚合物,在曝光后会脱去半缩醛(酮)保护基,半缩醛(酮)的活化能比较低,敏感性更高,脱保护后形成羟基结构,从而极性增大,溶解于碱性显影剂(一般为TMAH),该树脂单体具有曝光前后溶解度差异大,能够降低粗糙度,提高灵敏度和分辨率,有利于形成均一性良好的光刻图案,并且该树脂单体具有多环结构,更具耐刻蚀性能,酮结构增强了其亲水性,有利于提高碱溶性。
