    摘要: A method of fabricating an integrated circuit device includes forming first and second mask structures on respective first and second regions of a feature layer. Each of the first and second mask structures includes a dual mask pattern and an etch mask pattern thereon having an etch selectivity relative to the dual mask pattern. The etch mask patterns of the first and second mask structures are etched to partially remove the etch mask pattern from the second mask structure. Spacers are formed on opposing sidewalls of the first and second mask structures. The first mask structure is selectively removed from between the spacers in the first region to define a first mask pattern including the opposing sidewall spacers with a void therebetween in the first region, and a second mask pattern including the opposing sidewall spacers with the second mask structure therebetween in the second region.

    摘要: A method of fabricating an integrated circuit device includes forming first and second mask structures on respective first and second regions of a feature layer. Each of the first and second mask structures includes a dual mask pattern and an etch mask pattern thereon having an etch selectivity relative to the dual mask pattern. The etch mask patterns of the first and second mask structures are isotropically etched to remove the etch mask pattern from the first mask structure while maintaining at least a portion of the etch mask pattern on the second mask structure. Spacers are formed on opposing sidewalls of the first and second mask structures. The first mask structure is selectively removed from between the spacers in the first region using the portion of the etch mask pattern on the second mask structure as a mask to define a first mask pattern including the opposing sidewall spacers with a void therebetween in the first region, and a second mask pattern including the opposing sidewall spacers with the second mask structure therebetween in the second region. The feature layer may be patterned using the first mask pattern as a mask to define a first feature on the first region, and using the second mask pattern as a mask to define a second feature on the second region having a greater width than the first feature.

    摘要: A method of fabricating a semiconductor device facilitates the forming of a conductive pattern of features having different widths. A conductive layer is formed on a substrate, and a mask layer is formed on the conductive layer. First spaced apart patterns are formed on the mask layer and a second pattern including first and second parallel portion is formed beside the first patterns on the mask layer. First auxiliary masks are formed over ends of the first patterns, respectively, and a second auxiliary mask is formed over the second pattern as spanning the first and second portions of the second pattern. The mask layer is then etched to form first mask patterns below the first patterns and a second mask pattern below the second pattern. The first and second patterns and the first and second auxiliary masks are removed. The conductive layer is then etched using the first and second mask patterns as an etch mask.

    摘要: A first mask layer pattern including a plurality of parallel line portions is formed on an etch target layer on a semiconductor substrate. A sacrificial layer is formed on the first mask layer pattern and portions of the etch target layer between the parallel line portions of the first mask layer pattern. A second mask layer pattern is formed on the sacrificial layer, the second mask layer pattern including respective parallel lines disposed between respective adjacent ones of the parallel line portions of the first mask layer pattern, wherein adjacent line portions of the first mask layer pattern and the second mask layer pattern are separated by the sacrificial layer. A third mask layer pattern is formed including first and second portions covering respective first and second ends of the line portions of the first mask layer pattern and the second mask layer pattern and having an opening at the line portions of the first and second mask layer patterns between the first and second ends. The sacrificial layer and the etch target layer are etched using the third mask layer pattern, the first mask layer pattern and the second mask layer pattern as a mask to thereby form a plurality of parallel trenches in the etch target layer between the line portions of the first and second mask layer patterns. Conductive lines may be formed in the trenches.
