    摘要: A method of manufacturing a semiconductor device may include forming a sacrificial layer on a substrate including a first region and a second region, forming a first pattern on the sacrificial layer of the second region, forming a second pattern on the sacrificial layer of the first region, forming first upper spacers on opposite sidewalls of the second pattern, removing the second pattern, etching the first sacrificial layer of the first region using the first upper spacers as an etch mask to form a third pattern, etching the first sacrificial layer of the second region using the first pattern as an etch mask to form a fourth pattern, forming first lower spacers at either side of the third pattern, forming second spacers on opposite sidewalls of the fourth pattern, removing the third pattern and the fourth pattern, and etching the substrate using the first lower spacers and the second spacers as etch masks.

    摘要: A method includes forming a first etch target layer and a first mask layer on a substrate. Sacrificial patterns extending in a first direction are formed on the first mask layer in a second direction. Spacers are formed on sidewalls of the sacrificial patterns. After removing the sacrificial patterns, the first mask layer is etched using the spacers as an etching mask to form first masks. Second masks are formed on sidewalls of each first mask to define a third masks including each first mask and the second masks on sidewalls of each first mask. The first etch target layer is etched using the first and third masks as an etching mask to form first and second patterns in the first and second regions, respectively. Each first pattern has a first width, and each second pattern has a second width greater than the first width.
