    Abstract: A semiconductor device includes a substrate including an active pattern, a channel pattern and a source/drain pattern on the active pattern wherein the channel pattern includes semiconductor patterns vertically stacked and spaced apart from each other, the plurality of semiconductor patterns including a first semiconductor pattern and a neighboring second semiconductor pattern, and a gate electrode on the semiconductor patterns. The gate electrode includes an inner electrode between the first and second semiconductor patterns. The source/drain pattern includes a buffer layer and a main layer on the buffer layer. An indent region is defined in a vertical cross section of the device by the main layer, the first and second semiconductor patterns, and the inner electrode. The buffer layer is in the indent region. The buffer layer does not extend onto sidewalls of the first and second semiconductor patterns.
