    Abstract: A semiconductor device includes a substrate including a fin-type active region, the fin-type active region extending in a first direction; a plurality of channel layers on the fin-type active region, the plurality of channel layers including an uppermost channel layer, a lowermost channel layer, and an intermediate channel layer isolated from direct contact with each other in a direction perpendicular to an upper surface of the substrate; a gate electrode surrounding the plurality of channel layers and extending in a second direction intersecting the first direction; a gate insulating film between the plurality of channel layers and the gate electrode; and source/drain regions electrically connected to the plurality of channel layers. In a cross section taken in the second direction, the uppermost channel layer has a width greater than a width of the intermediate channel layer.

    Abstract: A semiconductor device includes a substrate. An active pattern extends in a first horizontal direction on the substrate. First to third nanosheets are sequentially spaced apart from each other in a vertical direction on the active pattern. A gate electrode extends in a second horizontal direction on the active pattern and surrounds the first to third nanosheets. A source/drain region includes a first layer disposed along side walls and a bottom surface of a source/drain trench and a second layer filling the source/drain trench. The second layer includes a first lower side wall facing a side wall of the first nanosheet and an opposite second lower side wall. A lower surface connects the first and second lower side walls and extends in the first horizontal direction. The first and second lower side walls of the second layer extend to have a constant slope in opposite directions to each other.

    Abstract: An integrated circuit (IC) device includes a fin-type active region extending in a first lateral direction on a substrate, a gate line extending in a second lateral direction on the fin-type active region, an insulating spacer covering a sidewall of the gate line, a source/drain region at a position adjacent to the gate line, a metal silicide film covering a top surface of the source/drain region, and a source/drain contact apart from the gate line with the insulating spacer therebetween in the first lateral direction. The source/drain contact includes a bottom contact segment being in contact with a top surface of the metal silicide film and an upper contact segment integrally connected to the bottom contact segment. A width of the bottom contact segment is greater than a width of at least a portion of the upper contact segment in the first lateral direction.
