Provided are an actinic ray-sensitive or radiation-sensitive resin composition; a resist film using the composition; and a pattern forming method. The actinic ray-sensitive or radiation-sensitive resin composition includes (A) a resin capable of increasing the solubility in an alkali developer by the action of an acid, the resin containing a repeating unit represented by formula (I), a repeating unit represented by formula (II) and a repeating unit represented by formula (III), and (B) a compound capable of generating a fluorine atom-containing acid upon irradiation with an actinic ray or radiation:
wherein each of R
1
and R
11
independently represents a hydrogen atom or an alkyl group which may have a substituent, and R
12
represents a phenyl group which may have a substituent.
提供了一种光致射线敏感或辐射敏感的树脂组合物;使用该组合物的光刻膜;以及一种图案形成方法。该光致射线敏感或辐射敏感的树脂组合物包括(A)一种树脂,能够通过酸的作用增加在碱性显影剂中的溶解度,该树脂含有由式(I)表示的重复单元、由式(II)表示的重复单元和由式(III)表示的重复单元;和(B)一种化合物,能够在光致射线或辐射照射下产生含氟酸基的酸:其中,R1和R11各自独立地表示氢原子或可能具有取代基的烷基,而R12表示可能具有取代基的苯基。
