摘要:
A negative resist composition that includes an alkali-soluble resin component, an acid generator component that generates acid upon exposure, and a cross-linker component, wherein the alkali-soluble resin component is a copolymer that includes a structural unit containing an aliphatic cyclic group having a fluorinated hydroxyalkyl group, and a structural unit derived from an acrylate ester that contains a hydroxyl group-containing aliphatic cyclic group, and the cross-linker component includes an alkylene urea-based cross-linker.
摘要:
There are provided a polymer compound which can form a resist pattern with excellent resolution, and a negative resist composition containing the polymer compound and a resist pattern-forming method thereof.The present invention is a polymer compound containing a structural unit (a0) represented by a general formula (a0-1) shown below. (wherein, R represents a hydrogen atom, a halogen atom, an alkyl group or a halogenated alkyl group; and R0 represents an alkyl group containing a hydroxyl group.)Also, the present invention is a negative resist composition, including: an alkali soluble resin component (A), an acid generator component (B) that generates acid upon exposure, and a cross-linking agent (C), wherein the alkali soluble resin component (A) contains a polymer compound (A1) having a structural unit (a0) represented by the general formula (a0-1) shown above.
