    摘要: A method of manufacturing a semiconductor device, including forming a molding layer; forming a damascene mask layer and mask layer on the molding layer; forming a mask layer pattern by etching the mask layer; forming a damascene pattern by partially etching the damascene mask layer; forming a damascene mask layer on the mask layer pattern to bury the damascene pattern; forming a damascene pattern partially overlapping the damascene pattern by etching the damascene mask layer and the mask layer pattern; connecting the damascene pattern and the damascene pattern by removing a portion of the mask layer pattern exposed by the damascene pattern; forming a damascene mask layer on the damascene mask layer to bury the damascene pattern; and forming a trench under the damascene patterns by etching the damascene mask layers and the molding layer using remaining portions of the mask layer pattern.

    摘要: An insulation layer is formed on a substrate. A first mask is formed on the insulation layer. The first mask includes a plurality of line patterns arranged in a second direction. The plurality of line patterns extend in a first direction substantially perpendicular to the second direction. A second mask is formed on the insulation layer and the first mask. The second mask includes an opening partially exposing the plurality of line patterns. The opening has an uneven boundary at one of a first end portion in the first direction and a second end portion in a third direction substantially opposite to the first direction. The insulation layer is partially removed using the first mask and the second mask as an etching mask, thereby forming a plurality of first trenches and second trenches. The plurality of first trenches and the second trenches are arranged in a staggered pattern.
