    摘要: A semiconductor device includes an active pattern on a substrate, a source/drain pattern on the active pattern, a channel pattern connected to the source/drain pattern, the channel pattern including semiconductor patterns stacked and spaced apart from each other, a gate electrode extending across the channel pattern, and inner spacers between the gate electrode and the source/drain pattern. The semiconductor patterns include stacked first and second semiconductor patterns. The gate electrode includes first and second portions, which are sequentially stacked between the substrate and the first and second semiconductor patterns, respectively. The inner spacers include first and second air gaps, between the first and second portions of the gate electrode and the source/drain pattern. The largest width of the first air gap is larger than that of the second air gap.

    摘要: Integrated circuit devices may include a fin-type active area, a semiconductor liner contacting a side wall of the fin-type active area and including a protrusion portion protruding outward from the fin-type active area in the vicinity of an edge of an upper surface of the fin-type active area, and an isolation layer spaced apart from the fin-type active area with the semiconductor liner therebetween. To manufacture the integrated circuit devices, a crystalline semiconductor layer covering the fin-type active area with a first thickness and an amorphous semiconductor layer covering the mask pattern with a second thickness may be formed, an extended crystalline semiconductor layer covering the mask pattern may be formed by crystalizing the amorphous semiconductor layer, and a semiconductor liner including a protrusion portion may be formed from the extended crystalline semiconductor layer and the crystalline semiconductor layer.

    摘要: An integrated circuit device includes a substrate including a device active region, a fin-type active region protruding from the substrate on the device active region, a gate line crossing the fin-type active region and overlapping a surface and opposite sidewalls of the fin-type active region, an insulating spacer disposed on sidewalls of the gate line, a source region and a drain region disposed on the fin-type active region at opposite sides of the gate line, a first conductive plug connected the source or drain regions, and a capping layer disposed on the gate line and extending parallel to the gate line. The capping layer includes a first part overlapping the gate line, and a second part overlapping the insulating spacer. The first and second parts have different compositions with respect to each other. The second part contacts the first part and the first conductive plug.
