Abstract
A method for manufacturing a semiconductor device includes forming features of a first mold pattern on a substrate including a first region and a second region, and forming a first insulation layer covering the first mold pattern from the first region to the second region. The method further includes forming a photoresist pattern on the first insulation layer in the second region, forming a second insulation layer covering the first insulation layer in the first region and the photoresist pattern in the second region from the first region to the second region, etching the second insulation layer, removing the photoresist pattern, and forming a first double patterning technology pattern having a first width in the first region and a second DPT pattern having a second width in the second region, wherein the second width is different from the first width.
