<p>PURPOSE: A photoresist composition is provided to obtain photoresist patterns with excellent shapes and profiles, for example, critical dimension uniformity, focus margin, mask error enhancement factor and line width roughness. CONSTITUTION: A photoresist composition comprises a resin, an acid generator and a compound represented by formula (C1), wherein Rc1 represents an aromatic group which can have one or more substituents, Rc2 and Rc3 independently each represent a hydrogen atom, an aliphatic hydrocarbon group which can have one or more substituents or an aromatic group which can have one or more substituents, Rc4 and Rc6 independently each represent a hydrogen atom or an aliphatic hydrocarbon group which can have one or more substituents, or Rc4 and Rc6 are bonded each other to form an alkanediyl group, Rc5 represents an aliphatic hydrocarbon group which can have one or more substituents or an amino group which can have one or two substituents, Rc7 represents a hydrogen atom or an aliphatic hydrocarbon group which can have one or more substituents, or Rc5 and Rc7 are bonded each other to form an alkanediyl group.</p> |
