摘要: An anti-reflective coating composition comprising a polyimide dissolved in an organic solvent is used to form an anti-reflective coating beneath a chemical amplification type resist layer. The composition allows a fine resist pattern to be formed with high accuracy in a convenient, efficient, reproducible manner.

摘要: In a chemically amplified positive resist composition comprising an organic solvent, an alkali soluble resin, an acid generator, and an optional dissolution inhibitor, a salt of a pyridine which may have an alkyl, alkoxy, amino or dialkylamino group with an alkylsulfonic acid, arylsulfonic acid or halogen atom is blended. Because of high sensitivity to deep UV and resolution and elimination of the PED problem causing T-top pattern configuration and the skirting phenomenon, the resist composition is improved in dimensional precision and lends itself to fine patterning.

摘要: A water-soluble composition comprising a water-soluble N-vinylpyrrolidone copolymer and a fluorinated organic acid in a weight ratio of from 20:80 to 70:30 is useful in forming a water-soluble overlying film on a chemically amplified resist layer. The overlying film functions as both an anti-reflective film and a protective film during resist pattern formation by photolithography.

摘要: A chemically amplified, positive resist composition contains a trifluoromethanesulfonic or p-toluenesulfonic acid bis- or tris(p-tert-butoxyphenyl)sulfonium salt and a nitrogenous compound. The composition is highly sensitive to high energy radiation, especially KrF excimer laser and has high sensitivity, resolution and plasma etching resistance while the resulting resist pattern is heat resistant.
