Abstract:
A multilayered body for photolithographic patterning of a photoresist layer which comprises, as an integrally layered body:(a) a substrate; (b) a water-insoluble anti-reflection film formed on the surface of the substrate in a thickness in the range from 30 to 300 nm; and (c) a photoresist layer having a thickness in the range from 200 to 500 nm formed on the anti-reflection film from a negative-working photoresist composition comprising, as a uniform solution in an organic solvent, (A) 100 parts by weight of an alkali-soluble resin; (B) from 0.5 to 20 parts by weight of an onium salt compound capable of releasing an acid by irradiation with actinic rays; (C) from 3 to 50 parts by weight of a glycoluril compound substituted by at least one hydroxyalkyl group or alkoxyalkyl group at the N-position; and (d) a water-soluble anti-reflection coating film formed on the photoresist layer.
