    摘要: 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.

    摘要: A method of forming a fine pattern of a semiconductor device using a fine pitch hard mask is provided. A first hard mask pattern including first line patterns formed on an etch target layer of a substrate with a first pitch is formed. A first layer including a top surface where a recess is formed between adjacent first line patterns is formed. A second hard mask pattern including second line patterns within the recess is formed. An anisotropic etching process is performed on the first layer using the first and the second line patterns as an etch mask. Another anisotropic etching process is performed on the etch target layer using the first and the second hard mask patterns as an etch mask.

    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.
