    摘要: PROBLEM TO BE SOLVED: To provide an active-ray sensitive or radiation-sensitive resin composition which is improved in development defects and distance dependence of a pattern, and to provide a method for forming a pattern that uses the composition. SOLUTION: The active-ray sensitive or radiation-sensitive resin composition comprises (A) a resin having a specified repeating unit having a norbornane structure in a side chain, and the solubility of which with an alkali developing solution is increased by an action of an acid; (B) a compound generating an acid by irradiation with active rays or radiation; and (C) a resin containing at least either a fluorine atom or a silicon atom and having a group that is decomposed by an action of an alkali developing solution, to increase the solubility with the alkali developing solution. The method for forming a pattern is carried out by using the composition. COPYRIGHT: (C)2011,JPO&INPIT
