    Abstract: A semiconductor device includes an active pattern including a lower pattern extending in a first direction, and a plurality of sheet patterns spaced apart from the lower pattern in a second direction. The sheet patterns include an uppermost sheet pattern and a plurality of gate structures on the lower pattern and spaced apart from each other in the first direction. Each of the plurality of gate structures includes a gate electrode and a gate insulating film and a source/drain pattern between adjacent ones of the plurality of gate structures. Each of inner gate structures includes a gate electrode and a gate insulating film. A semiconductor liner film includes silicon-germanium, and contacts the gate insulating film of each of the inner gate structures. A portion of the semiconductor liner film protrudes upwardly in the first direction beyond an upper surface of the uppermost sheet pattern.
