Patent ID: 7432034

Claim:
A negative resist composition comprising: (A) an alkali-soluble resin; (B-1) a cross-linking agent capable of cross-linking with the alkali-soluble resin (A) by the action of an acid, in which the cross-linking agent is not a resin and is a phenol compound having a molecular weight of 2,000 or below and containing: at least one phenolic hydroxyl group; 3 to 5 benzene rings in the molecule; and at least two cross-linking groups bonded to any of the benzene rings, the cross-linking group being a group selected from the group consisting of a hydroxymethyl group, an alkoxymethyl group and an acyloxymethyl group; (B-2) a cross-linking agent capable of cross-linking with the alkali-soluble resin (A) by the action of an acid, in which the cross-linking agent contains at least two groups selected from the group consisting of the groups represented by the following formulae (1) and (2); (C) a compound capable of generating an acid upon irradiation with an actinic ray or radiation; and (D) a nitrogen-containing basic compound: wherein R 3 represents a hydrogen atom, an alkyl group, or an alkylcarbonyl group; and R 4 and R 5 each represents a hydrogen atom, an alkyl group or an alkylcarbonyl group.
