    Abstract: An integrated circuit (IC) device includes a fin-type active region extending lengthwise in a first direction, a plurality of nanosheets overlapping each other in a second direction on a fin top surface of the fin-type active region, and a source/drain region on the fin-type active region and facing the plurality of nanosheets in the first direction. The plurality of nanosheets include a first nanosheet, which is closest to the fin top surface of the fin-type active region and has a shortest length in the first direction, from among the plurality of nanosheets. The source/drain region includes a source/drain main region and a first source/drain protruding region protruding from the source/drain main region. The first source/drain protruding region protrudes from the source/drain main region toward the first nanosheet and overlaps portions of the plurality of nanosheets in the second direction.

    Abstract: A semiconductor device includes first and second channels, first and second gate structures, first and second source/drain layers, first and second fin spacers, and first and second etch stop patterns. The first channels are disposed vertically on a first region of a substrate. The second channels are disposed vertically on a second region of the substrate. The first gate structure is formed on the first region and covers the first channels. The second gate structure is formed on the second region and covers the second channels. The first and second source/drain layers contact the first and second channels, respectively. The first and second fin spacers contact sidewalls and upper surfaces of the first and second source/drain layers, respectively. The first and second etch stop patterns are formed on the first and second fin spacers, respectively, and do not contact the first and second source/drain layers, respectively.
