    摘要: A method of fabricating an integrated circuit device includes forming first and second preliminary mask structures on a hard mask layer in respective first and second regions of the substrate. Spacers are formed on opposing sidewalls of the first and second preliminary mask structures, and the first preliminary mask structure is selectively removed from between the spacers in the first region. The hard mask layer is etched using the spacers and the second preliminary 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 and the second preliminary mask structure therebetween in the second region. An insulation layer is patterned using the first and second mask patterns as respective masks to define a first trench in the first region and a second trench in the second region having a greater width than the first trench, and first and second conductive patterns are formed in the first and second trenches.

    摘要: Methods of forming integrated circuit devices utilize fine width patterning techniques to define conductive or insulating patterns having relatively narrow and relative wide lateral dimensions. A target material layer is formed on a substrate and first and second mask layers of different material are formed in sequence on the target material layer. The second mask layer is selectively etched to define a first pattern therein. Sidewall spacers are formed on opposing sidewalls of the first pattern. The first pattern and sidewall spacers are used collectively as an etching mask during a step to selectively etch the first mask layer to define a second pattern therein. The first pattern is removed to define an opening between the sidewall spacers. The first mask layer is selectively re-etched to convert the second pattern into at least a third pattern, using the sidewall spacers as an etching mask. The target material layer is selectively etched using the third pattern as an etching mask.
