摘要:
An actinic ray-sensitive or radiation-sensitive resin composition capable of forming a hole pattern which has an ultrafine pore diameter (for example, 60 nm or less) and has an excellent cross-sectional shape with excellent local pattern dimensional uniformity; and a resist film, a pattern forming method, a method for preparing an electronic device, and an electronic device, each using the same, are provided. The actinic ray-sensitive or radiation-sensitive resin composition includes (P) a resin containing 30 mol % or more of a repeating unit (a) represented by the following general formula (I) based on all the repeating units; (B) a compound capable of generating an acid upon irradiation of actinic rays or radiation; and (G) a compound having at least one of a fluorine atom and a silicon atom, and further having basicity or being capable of increasing the basicity by an action of an acid:

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
