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.

摘要:
In a photoresist composition for a semiconductor manufacturing process and a method of forming a photoresist pattern using the photoresist composition, the photoresist composition includes an organic dispersing agent for dispersing acid (H+). The photoresist film may have enough spaces among photosensitive polymers so that acid may be dispersed sufficiently in an exposure process. Thus, a photoresist pattern may be easily formed in a defocus region. Defects in a semiconductor device may be reduced and a productivity of the semiconductor manufacturing process may be enhanced.
