    摘要: A method of forming a protection layer on a photoresist pattern and a method of forming a fine pattern using the same are provided. A photoresist layer may be formed on a substrate. Exposure regions and non-exposure regions may be defined in the photoresist layer by an exposure process. A reactive material layer may be formed on the photoresist layer having the exposure regions. A protection layer may be formed on the exposure regions by the reactive material layer reacting via a chemical attachment process. The non-exposure regions and the reactive material layer that remains after the reaction may be removed by a development process to form photoresist patterns. The substrate may be etched using the protection layer and the photoresist patterns as etching masks.

    摘要: In polymers for an anti-reflective coating, compositions for an anti-reflective coating and methods of forming a pattern of a semiconductor device using the same, the compositions for an anti-reflective coating include a polymer that includes a first repeating unit having a basic side group, a second repeating unit having a light-absorbing group, and a third repeating unit having a cross-linkable group; a photoacid generator; a cross-linking agent; and a solvent. The polymer for the anti-reflective coating, which may have a basic side group chemically bound to a backbone of the polymer, may properly adjust diffusion of an acid in an anti-reflective coating layer to improve the profile of a pattern.
