Patent ID: 7416837

Claim:
A method for preparing a pattern, comprising: forming a resist pattern; and coating a resist pattern-improving material on the surface of the resist pattern, wherein the resist pattern-improving material is mixed with the resist pattern at the interface therebetween, wherein the resist pattern-improving material comprises: (a) a water-soluble or alkali-soluble composition, comprising: (i) a resin, and (ii) a crosslinking agent or nonionic surfactant, and (b) a water-soluble aromatic compound, wherein the water-soluble aromatic compound is selected from the group consisting of polyhydric phenols represented by gallic acid, and derivatives thereof; naphthalene polyhydric alcohols represented by naphthalenediol, naphthalenetriol, and derivatives thereof; and benzophenone derivative represented by alizarin yellow A, wherein the resist pattern is formed by irradiating an ArF excimar laser light or a laser light having a wavelength shorter than that of the ArF excimar laser light, and wherein the pattern of the resist pattern-improving material includes a base resin which does not substantially transmit the ArF excimar laser light.
