A method of correcting an optical parameter in a photomask is provided. The method includes providing a photomask, exposing the photomask, detecting an aerial image to estimate the photomask, and irradiating gas cluster ion beams to the photomask based on an estimation result to correct the optical parameter in the photomask in relation to the aerial image. The gas cluster ion beams may be irradiated to a front surface of the photomask on which a mask pattern is formed or a rear surface of the photomask on which the mask pattern is not formed.

Provided is a method for forming patterns of a semiconductor device. According to the method, first mask patterns may be formed on a substrate, and second mask patterns may be formed on sidewalls of each first mask pattern. Third mask patterns may fill spaces formed between adjacent second mask patterns, and the second mask patterns may be removed. A portion of the substrate may then be removed using the first and third mask patterns as etch masks.
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.
