    Abstract: A semiconductor device includes a substrate; an active region extending in a first, horizontal, direction on the substrate, and including a first active pattern at a first height above a bottom surface of the substrate in a vertical direction and having a first width in a second, horizontal, direction, a second active pattern having a second width in the second direction different from the first width, and a transition active pattern connecting the first active pattern to the second active pattern; gate structures intersecting the active region each gate structure extending in the second direction across the substrate; source/drain regions disposed on sides of the gate structures, and including a first source/drain region disposed on the first active pattern, a second source/drain region disposed on the second active pattern, and a transition source/drain region disposed on the transition active pattern. Each of the source/drain regions is disposed on the active region and includes a first epitaxial layer having a recessed upper surface and a second epitaxial layer disposed on the first epitaxial layer, at a second height above a bottom surface of the substrate in a vertical direction, a first sidewall thickness of the first epitaxial layer of the first source/drain region in the first direction is different from a second sidewall thickness of the first epitaxial layer of the second source/drain region in the first direction, at the second height, thicknesses of opposing sidewalls of the first epitaxial layer of the transition source/drain region in the first direction are different, and a vertical level of a lowermost end of the second epitaxial layer of the first source/drain region, a vertical level of a lowermost end of the second epitaxial layer of the second source/drain region, and a vertical level of a lowermost end of the second epitaxial layer of the transition source/drain region are different from each other.

    Abstract: An integrated circuit device includes a fin-type active region on a substrate; at least one nanosheet having a bottom surface facing the fin top; a gate line on the fin-type active region; and a source/drain region on the fin-type active region, adjacent to the gate line, and in contact with the at least one nanosheet, wherein the source/drain region includes a lower main body layer and an upper main body layer, a top surface of the lower main body layer includes a lower facet declining toward the substrate as it extends in a direction from the at least one nanosheet to a center of the source/drain region, and the upper main body layer includes a bottom surface contacting the lower facet and a top surface having an upper facet. With respect to a vertical cross section, the lower facet extends along a corresponding first line and the upper facet extends along a second line that intersects the first line.

    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.
