Patent ID: 8470509

Claim:
A negative resist composition comprising at least: (A) a base resin that is alkaline-soluble and is made alkaline-insoluble by action of an acid, and/or a combination of a base resin that is alkaline-soluble and is made alkaline-insoluble by reaction with a crosslinker by action of an acid, with a crosslinker; (B) an acid generator; and (C) a compound containing a nitrogen atom as a basic component, wherein the base resin contains at least repeating units represented by the following general formula (1), general formula (2), and general formula (4) and has a weight average molecular weight of 1,000 to 10,000, wherein each R 1 and R 2 independently represents a hydrogen atom or a methyl group, X represents one or more groups selected from a linear, a branched, or a cyclic alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms and a thioalkyl group having 1 to 10 carbon atoms, m and n represent an integer of 1 to 4, R 5 represents a hydrogen atom, a hydroxyl group, an alkyl group having 1 to 10 carbon atoms or an alkoxy group having 1 to 10 carbon atoms, and v represents an integer of 0 to 5, and the compound containing a nitrogen atom as a basic component contains at least one or more kinds of amine compounds having a carboxyl group and not having a hydrogen atom covalently bonded to a base-center nitrogen atom, wherein the base-center nitrogen atom is not included in an aromatic ring.
