Abstract:
Provided is a novolac resin having excellent developability, heat resistance, and dry etching resistance, and a resist film. A novolac resin includes a cyclic novolac resin (A) having a molecular structure represented by Structural Formula (1): (in the formula, α is a structural moiety (α) represented by Structural Formula (2): n is an integer of 2 to 10),in which at least one of X's present in the resin is any one of a tertiary alkyl group, an alkoxyalkyl group, an acyl group, an alkoxycarbonyl group, a hetero atom-containing cyclic hydrocarbon group, and a trialkylsilyl group, at least one of the structural moieties (α) present in the resin is a structural moiety (α1) in which l is 1, and at least one thereof is a structural moiety (α2) in which l is 2.

Claim (Index 1):
A novolac resin comprising:\n a cyclic novolac resin (A) having a molecular structure represented by Structural Formula (1): wherein \u03b1 is a structural moiety (\u03b1) represented by Structural Formula (2): wherein R 1  is any one of an alkyl group which may have a substituent, and an aryl group which may have a substituent, R 2 's each independently represent any one of a hydrogen atom, an alkyl group, an alkoxy group, and a halogen atom, and may be bonded to any carbon atom on the naphthalene ring, m is an integer of 1 to 5, X is any one of a hydrogen atom, a tertiary alkyl group, an alkoxyalkyl group, an acyl group, an alkoxycarbonyl group, a hetero atom-containing cyclic hydrocarbon group, and a trialkylsilyl group, an \u2014OX group may be bonded to any carbon atom on the naphthalene ring, and l is 1 or 2), and n is an integer of 2 to 10 and an acyclic novolac resin (B) having the structural moiety (\u03b1) as a repeating unit, wherein at least one of X's present in the resin is any one of a tertiary alkyl group, an alkoxyalkyl group, an acyl group, an alkoxycarbonyl group, a hetero atom-containing cyclic hydrocarbon group, and a trialkylsilyl group, at least one of the structural moieties (\u03b1) present in the resin is a structural moiety (\u03b11) in which l is 1, and at least one thereof is a structural moiety (\u03b12) in which l is 2.
