    摘要: Disclosed is a method of forming a pattern. A first organic polymer layer is formed on a substrate on which an underlying layer, and then a second organic polymer layer, which has an opening partially exposing the first organic polymer layer, is formed on the first organic polymer layer. Next, a silicon-containing polymer layer is formed on the second organic polymer layer to cover the opening. The silicon-containing polymer layer is oxidized and simultaneously the second organic polymer layer and the first organic polymer layer are ashed by oxygen plasma to form a pattern having an anisotropy-shape. The underlying layer is etched using the silicon-containing polymer layer and the first organic polymer layer as an etching mask to form a pattern.

    摘要: A method and mask having balance patterns for reducing and/or preventing chemical flare from occurring in a photoresist between a first mask region and a second mask region. Balance patterns formed on the mask may have a desired and/or predetermined pitch and may be regularly arranged. If the pitch of the balance patterns is equal to or smaller than a threshold value, the balance patterns may not allow the patterns to be transferred onto a photoresist. In addition, the photoresist corresponding to the balance patterns may be either completely removed or completely remain depending on the duty of the balance patterns.
