Patent ID: 7981588

Claim:
A negative resist composition comprising an alkali soluble base component (A), an acid generator component (B) that generates acid by exposure, and a cross-linking agent component (C), wherein said base component (A) comprises a polyhydric phenol compound (A1) containing two or more phenolic hydroxyl groups represented by the following general formula (I), with a molecular weight of 300 to 2500 and the proportion of said polyhydric phenol compound (A1) is more than 50% by weight in said component (A): where in the formula (I), R 11 to R 17 each represent, independently, an alkyl group of 1 to 10 carbon atoms, or an aromatic hydrocarbon group, which may contain hetero atoms in the structure; g and j each represent, independently, an integer of 1 or more; k and q each represent, independently, an integer of 0 or more; g+j+k+q is 5 or less; h represents an integer of 1 or more; 1 and m each represent, independently, an integer of 0 or more; h+1+m is 4 or less; i represents an integer of 0 or more ; n and o each represent, independently, an integer of 0 or more; i+n+o is 4 or less; p represents 0 or 1; and X is a group represented by the following general formula (Ia) or (Ib): where in the formula (Ia), R 18 and R 19 each represent, independently, an alkyl group of 1 to 10 carbon atoms, or an aromatic hydrocarbon group, which may contain hetero atoms in the structure; r, y, and z each represent, independently, an integer of 0 or more, and r+y+z is 4 or less.
