Abstract: A semiconductor device includes a first active pattern having a first lower pattern and a first sheet pattern on the first lower pattern. First gate structures include a first gate electrode. A second active pattern includes a second lower pattern. A second sheet pattern is on the second lower pattern. Second gate structures include a second gate electrode that surrounds the second sheet pattern. A first source/drain recess is between adjacent first gate structures. A second source/drain recess is between adjacent second gate structures. A first source/drain pattern extends along the first source/drain recess. A first silicon germanium filling film is on the first silicon germanium liner. A second source/drain pattern includes a second silicon germanium liner extending along the second source/drain recess. A second silicon germanium filling film is on the second silicon germanium liner.

Abstract: A semiconductor device includes a substrate including a first region and a second region, a first active pattern on the first region, a first gate structure having a first width in the first direction, on the first active pattern, a first epitaxial pattern disposed in the first active pattern on a side surface of the first gate structure, a second active pattern on the second region, a second gate structure having a second width greater than the first width in the first direction, on the second active pattern and a second epitaxial pattern disposed in the second active pattern on a side surface of the second gate structure. Each of the first epitaxial pattern and the second epitaxial pattern includes silicon germanium (SiGe), and a first Ge concentration of the first epitaxial pattern is lower than a second Ge concentration of the second epitaxial pattern.
