Abstract: A method includes forming an active pattern on a substrate, the active pattern comprising first semiconductor patterns and second semiconductor patterns, which are alternately stacked, forming a capping pattern on a top surface and a sidewall of the active pattern, performing a deposition process on the capping pattern to form an insulating layer, and forming a sacrificial gate pattern intersecting the active pattern on the insulating layer. The capping pattern has a crystalline structure and is in physical contact with sidewalls of the first semiconductor patterns and sidewalls of the second semiconductor patterns.

Abstract: A semiconductor device includes an active pattern on a substrate, a pair of source/drain patterns on the active pattern, a channel pattern between the pair of source/drain patterns, the channel pattern including semiconductor patterns stacked to be spaced apart from each other, and a gate electrode crossing the channel pattern and extending in a first direction. One of the pair of source/drain patterns includes a first semiconductor layer and a second semiconductor layer thereon. The first semiconductor layer is in contact with a first semiconductor pattern, which is one of the stacked semiconductor patterns. The largest widths of the first semiconductor pattern, the first semiconductor layer, and the second semiconductor layer in the first direction are a first width, a second width, a third width, respectively, and the second width is larger than the first width and smaller than the third width.
