摘要: A method of manufacturing a semiconductor device includes forming an interlayer dielectric film that has first and second trenches on first and second regions of a substrate, respectively, forming a first metal layer along a sidewall and a bottom surface of the first trench and along a top surface of the interlayer dielectric film in the first region, forming a second metal layer along a sidewall and a bottom surface of the second trench and along a top surface of the interlayer dielectric film in the second region, forming a first sacrificial layer pattern on the first metal layer such that the first sacrificial layer fills a portion of the first trench, forming a first electrode layer by etching the first metal layer and the second metal layer using the first sacrificial layer pattern, and removing the first sacrificial layer pattern.
