    Abstract: A semiconductor device includes a semiconductor substrate having first and second regions therein, a first lower semiconductor pattern, which protrudes from the semiconductor substrate in the first region and extends in a first direction across the semiconductor substrate, and a first gate electrode, which extends across the first lower semiconductor pattern and the semiconductor substrate in a second direction. A plurality of semiconductor sheet patterns are provided, which are spaced apart from each other in a third direction to thereby define a vertical stack of semiconductor sheet patterns, on the first lower semiconductor pattern. A first gate insulating film is provided, which separates the plurality of semiconductor sheet patterns from the first gate electrode. A second lower semiconductor pattern is provided, which protrudes from the semiconductor substrate in the second region. A plurality of wire patterns are provided, which are spaced apart from each other on the second lower semiconductor pattern. A second gate insulating film is wrapped around each of the plurality of wire patterns.

    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.
