    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.

    摘要: Semiconductor devices may include a substrate, gate electrodes on the substrate, and source/drain regions at both sides of each of the gate electrodes. Each of the gate electrodes may include a gate insulating pattern on the substrate, a lower work-function electrode pattern that is on the gate insulating pattern and has a recessed upper surface, and an upper work-function electrode pattern that conformally extends on the recessed upper surface of the lower work-function electrode pattern. Topmost surfaces of the lower work-function electrode patterns may be disposed at an equal level, and the upper work-function electrode patterns may have different thicknesses from each other.
