Patent ID: 7033731

Claim:
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 which is a copolymeric resin having a weight-average molecular weight of 2000 to 4000 and consisting of 60 to 97% by moles of hydroxystyrene units and 40 to 3% by moles of styrene units; (B) from 0.5 to 20 parts by weight of an onium salt compound having an anionic part which is the fluoroalkyl sulfonate anion, said salt being 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) from 0.01 to 1.0 part by weight of an aliphatic amine compound per 100 parts by weight of the component (A).
