    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: In a method of forming a semiconductor device, a feature layer is provided on a substrate and a mask layer is provided on the feature layer. A portion of the mask layer is removed in a first region of the semiconductor device where fine features of the feature layer are to be located, the mask layer remaining in a second region of the semiconductor device where broad features of the feature layer are to be located. A mold mask pattern is provided on the feature layer in the first region and on the mask layer in the second region. A spacer layer is provided on the mold mask pattern in the first region and in the second region. An etching process is performed to etch the spacer layer so that spacers remain at sidewalls of pattern features of the mold mask pattern, and to etch the mask layer in the second region to provide mask layer patterns in the second region. The feature layer is etched using the mask layer patterns as an etch mask in the second region and using the spacers as an etch mask in the first region to provide a feature layer pattern having fine features in the first region and broad features in the second region.
