摘要:
A base-loaded polymer is applied to a semiconductor feature formed after exposing and developing a photoresist layer in order to reduce line edge roughness caused by a residual acid collecting on the edges of the feature during the post-exposure bake of the photoresist. Alternatively, a polymer is applied containing grains that are of suitable for smoothing the line edge roughness.
