Abstract:
A single imaging process for manufacturing semiconductor devices wherein comprises using an amplified silicon-containing negative-tone resist composition as a conventional single layer resist; wherein saidamplified silicon-containing negative-tone resist composition comprises (a) about 0.1 to about 50 wt. % of an aqueous base soluble silicon-containing polymer having phenolic group for O-alkylation (b) about 0.005 to about 40 wt. % of an acid catalyzable crosslinking agent capable of crosslinking the silicon-containing polymer at the hydroxyl site of the phenolic group (c) about 0.001 to about 14 wt. % of an acid generator; (d) about 40 to about 99.5 wt. % of a solvent for the polymer resin, and (e) about 0.001 to about 8 wt. of a photosensitizer that is capable of absorbing irradiation in the mid-UV, deep-UV, deep V, extreme-UV, X-ray, e-beam or ion-beam range; (f) about 0.001 to about 16 wt. % of a base, (g) about 100 to about 1000 PPM of a surfactant.
