Abstract:
1. A process for manufacturing a semiconductor device comprising: forming a resist pattern by applying a resist pattern thickening material to cover a surface of a resist pattern to be thickened to thicken the resist pattern to be thickened to form the resist pattern, after forming the resist pattern to be thickened on an underlying layer; and patterning the underlying layer by performing an etching using the resist pattern formed in forming the resist pattern which is thickened as a mask, wherein the resist pattern thickening material comprises a resin, a cross-linking agent, and a compound having a cyclic structure which is selected from an aromatic compound, an alicyclic compound, and a heterocyclic compound; and pure water, wherein the aromatic compound is selected from a polyphenol compound, a naphthalene polyvalent alcohol compound, a benzophenone compound, a flavonoid compound, and derivatives and glycosides thereof, the alicyclic compound is selected from polycycloalkane, cycloalkane, steroids, derivatives and glycosides thereof, and the heterocyclic compound is selected from pyrrolidine, pyridine, imidazole, morpholine, furan, pyran, and saccharides.
