ACTINIC-RAY-SENSITIVE OR RADIATION-SENSITIVE RESIN COMPOSITION, AND RESIST FILM AND PATTERN FORMING METHOD USING THE SAME COMPOSITION

摘要

An object of the present invention is to provide an actinic-ray-sensitive or radiation-sensitive resin composition which is significantly excellent in terms of exposure latitude, is capable of forming a favorable rectangular pattern profile, and exhibits low dissolution of the components into an immersion liquid when performing immersion exposure, and a resist film and a pattern forming method each using the same composition. The actinic-ray-sensitive or radiation-sensitive resin composition contains (A) a compound represented by formula (I) and capable of generating an acid upon irradiation of actinic-rays or radiations, and (B) a resin capable of increasing the solubility in an alkaline developer by the action of an acid.
