    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.
