ACTINIC RAY SENSITIVE OR RADIATION SENSITIVE RESIN COMPOSITION, RESIST FILM AND PATTERN FORMING METHOD USING SAID COMPOSITION, AND METHOD FOR MANUFACTURING ELECTRONIC DEVICE AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an actinic ray sensitive resin composition which is excellent in exposure latitude and generates little scum, a resist film formed using the composition, and a pattern forming method using the composition, and to provide a method for manufacturing an electronic device and an electronic device.SOLUTION: An actinic ray sensitive resin composition contains (A) a resin having a repeating unit represented by the following general formula (1) and a repeating unit which is decomposed by an action of an acid to generate an alkali-soluble group, and (B) a compound, represented by the following general formula (Z-1), which generates an acid by irradiation with an actinic ray. K represents a cyclic acid anhydride group, and A represents a cyclic organic group.
