Resist composition containing specific cross-linking agent

Abstract

A resist composition comprising an alkali-soluble polymer, a special cross-linking agent containing one or more oxirane rings and at least one of —O—, —CO—,—COO— and —OCO— groups in the molecule, a photoacid generator, and a solvent can form a film having high transmittance for deep UV light such as ArF excimer laser beams and high etching resistance as well as high resolution, and thus suitable for forming a negative working pattern.
