    Abstract: A semiconductor device includes a first active region, a second active region spaced apart from the first active region, a plurality of first channel layers disposed on the first active region, and a second channel layer disposed on the second active region. The semiconductor device further includes a first gate structure intersecting the first active region and the first channel layers, a second gate structure intersecting the second active region and the second channel layer, a first source/drain region disposed on the first active region and contacting the plurality of first channel layers, and a second source/drain region and contacting the second channel layer. The plurality of first channel layers includes a first uppermost channel layer and first lower channel layers disposed below the first uppermost channel layer, and the first uppermost channel layer includes a material that is different from a material included in the first lower channel layers.

    Abstract: A semiconductor device includes a first active fin protruding from a substrate, a first gate pattern covering a side surface and a top surface of the first active fin, and first source/drain patterns at opposite sides of the first gate pattern, each of the first source/drain patterns including a first lower side and a second lower side spaced apart from each other, a first upper side extended from the first lower side, a second upper side extended from the second lower side. The first lower side may be inclined at a first angle relative to a top surface of the substrate, the second upper side may be inclined at a second angle relative to the top surface of the substrate, and the first angle may be greater than the second angle.
