    摘要: A chemically amplified negative resist composition is provided comprising (A) an alkali-soluble polymer, (B) an acid generator, and (C) a nitrogen-containing compound as a basic component, the polymer (A) turning alkali insoluble under the catalysis of acid. A basic polymer having a secondary or tertiary amine structure on a side chain serves as components (A) and (C). Processing the negative resist composition by EB or EUV lithography process may form a fine size resist pattern with advantages including uniform diffusion of base, improved LER, controlled deactivation of acid at the substrate interface, and a reduced degree of undercut.
