ABSTRACT:
A compound including a polyhydric phenol compound represented by general formula (I) shown below (wherein R11to R17each independently represents an alkyl group of 1 to 10 carbon atoms or aromatic hydrocarbon group which may contain a hetero atom in the structure thereof, and X represents an aliphatic cyclic group) and having a molecular weight of 300 to 2,500, in which some or all of the hydrogen atoms of the phenolic hydroxyl groups are substituted with acid dissociable, dissolution inhibiting groups; a positive resist composition containing the compound; and a method of forming a resist pattern using the positive resist composition.
