A resist composition which can easily form a resist pattern excellent in transparency for vacuum ultraviolet rays such as an F2 excimer laser or the like and dry etching characteristics and further excellent in sensitivity, resolution, flatness, thermal resistance and the like, is provided.
The resist composition, characterized by comprising (A) a fluorine-containing polymer having an acidic group blocked with a blocking group containing a cycloalkyl group, an organic group having one or more of cycloalkyl groups, a bicycloalkyl group or the like, (B) an acid generating compound capable of generating an acid by irradiation with a light, and (C) an organic solvent.
本发明提供了一种抗蚀剂组合物,该抗蚀剂组合物可以很容易地形成对 F2 准分子激光等真空紫外线具有优异透明度和干蚀刻特性的抗蚀图案,而且在灵敏度、分辨率、平整度、耐热性等方面也具有优异的性能。
这种抗蚀剂组合物的特点是:(A) 含氟聚合物,其酸性基团被含有环烷基的封端基团、具有一个或多个环烷基的有机基团、双环烷基或类似基团的封端基团封住;(B) 酸生成化合物,能够通过光照射生成酸;(C) 有机溶剂。
