    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: Methods of fabricating a semiconductor device are provided. Methods of forming a finer pattern of a semiconductor device using a buffer layer for retarding, or preventing, bridge formation between patterns in the formation of a finer pattern below resolution limits of a photolithography process by double patterning are also provided. A first hard mask layer and/or a second hard mask layer may be formed on a layer of a substrate to be etched. A first etch mask pattern of a first pitch may be formed on the second hard mask layer. After a buffer layer is formed on the overall surface of the substrate, a second etch mask pattern of a second pitch may be formed thereon in a region between the first etch mask pattern. The buffer layer may be anisotropically etched using the second etch mask pattern as an etch mask, forming a buffer layer pattern. The second hard mask layer may be anisotropically etched using the first etch mask pattern and/or the buffer layer pattern as etch masks, forming a second hard mask pattern. The first hard mask layer may be anisotropically etched using the second hard mask pattern as an etch mask, forming a first hard mask pattern. The etched layer may be anisotropically etched using the first hard mask pattern as an etch mask.

    摘要: Mask sets are provided which may be used to define a first pattern region that has a first pitch pattern and a second pattern region that has a second pitch pattern during the fabrication of a semiconductor device. These mask sets may include a first mask that has a first exposure region in which a first halftone pattern defines the first pattern region and a first screen region in which a first shield layer covers the second pattern region. These mask sets may further include a second mask that has a second exposure region in which a second halftone pattern defines the second pattern region and a second screen region in which a second shield layer covers the first pattern region. The second shield layer also extends from the second screen region to cover a portion of the second halftone pattern.
