    Abstract: A semiconductor device includes: an active pattern extending in a first direction on a substrate; a first lower source/drain pattern and a second lower source/drain pattern provided on the active pattern and spaced apart from each other in the first direction; a first upper source/drain pattern provided on the first lower source/drain pattern; a second upper source/drain pattern provided on the second lower source/drain pattern; and a gate electrode crossing the active pattern and extending in a second direction intersecting the first direction. The gate electrode includes an overlapping portion overlapping the active pattern in a third direction perpendicular to the first direction and the second direction. A length of the overlapping portion in the second direction is less than a length of the first lower source/drain pattern in the second direction.

    Abstract: A semiconductor device includes a lower channel pattern and an upper channel pattern stacked on a substrate in a first direction perpendicular to a top surface of the substrate, lower source/drain patterns on the substrate and at a first side and a second side of the lower channel pattern, upper source/drain patterns stacked on the lower source/drain patterns and at a third side and a fourth side of the upper channel pattern, a first barrier pattern between the lower source/drain patterns and the upper source/drain patterns, and a second barrier pattern between the first barrier pattern and the upper source/drain patterns. The first barrier pattern includes a first material and the second barrier pattern includes a second material, wherein the first material and the second material are different.

    Abstract: A semiconductor device comprises a substrate, a first active pattern on the substrate and extending in a first direction, a second active pattern extending in the first direction spaced apart from the substrate, a gate electrode extending in a second direction surrounding the first and second active patterns, and a high dielectric film between the first and second active patterns and the gate electrode. The gate electrode includes first and second work function adjusting films surrounding the high dielectric film on the first and second active patterns, and a filling conductive film surrounding the first and second work function adjusting films. The first and second work function adjusting films include first and second work function conductive films, each of which includes a first metal film. A thickness of the first metal film of the first work function conductive film is greater than that of the second work function conductive film.
