    Abstract: A semiconductor device includes a substrate including an active pattern, a channel pattern on the active pattern and including semiconductor patterns, a source/drain pattern connected to the semiconductor patterns, a gate electrode on the semiconductor patterns, and a gate dielectric layer between the gate electrode and the semiconductor patterns. An inner spacer of the gate dielectric layer includes a horizontal portion between the high-k dielectric layer and the second semiconductor pattern, a vertical portion between the high-k dielectric layer and the source/drain pattern, and a corner portion between the horizontal portion and the vertical portion. A first thickness of the horizontal portion is less than a second thickness of the vertical portion. The second thickness of the vertical portion is less than a third thickness of the corner portion.

    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.
