    Abstract: A semiconductor device includes a device isolation layer on a substrate; pattern groups including fin patterns extending in a first direction; and gate structures extending in a second direction to intersect the fin patterns. A first pattern group, among the pattern groups, may include first fin patterns. At least a portion of the first fin patterns may be arranged with a first pitch in the second direction. The first pattern group may include a first planar portion extending from a first recess portion. A central axis of the first recess portion may be spaced apart from a central axis of one of the first fin patterns by a first distance in the second direction. The first planar portion may have a first width in the second direction and being greater than the first pitch.. The first distance may be about 0.8 times to about 1.2 times the first pitch.

    Abstract: A semiconductor device includes a substrate including a boundary region between first and second regions, first active patterns on the first region, second active patterns on the second region, and an isolation insulating pattern on the boundary region between the first and second active patterns. A width of at least some of the first active patterns have different widths. Widths of the second active patterns may be equal to each other. A bottom surface of the isolation insulating pattern includes a first bottom surface adjacent to a corresponding first active pattern, a second bottom surface adjacent to a corresponding second active pattern, and a third bottom surface between the first bottom surface and the second bottom surface. The third bottom surface is located at a different height from those of the first and second bottom surfaces with respect to a bottom surface of the substrate.

    Abstract: A semiconductor device may include a device isolation layer on a substrate and defining active regions extending a first direction; gate structures intersecting the active regions and extending in a second direction; channel layers spaced apart from each other on the active regions and surrounded by the gate structures; and source/drain regions connected to the channel layers and in recessed regions of the active regions on both sides of the gate structures. First and second regions of the substrate respectively may be spaced apart by a first length and the second length from first ends of the gate structures in the second direction. The second length may be longer than the first length. An upper surface of the device isolation layer may have recessed portion on the first region of the substrate and a flat upper surface on the second region of the substrate.

    Abstract: A method of forming fine patterns includes forming an upper mask layer on a substrate, forming preliminary mask patterns on the upper mask layer, and forming upper mask patterns by etching the upper mask layer using the preliminary mask patterns as etch masks. Forming the upper mask patterns includes etching the upper mask layer by performing an etching process using an ion beam. The upper mask patterns include a first upper mask pattern formed under each of the preliminary mask patterns, and a second upper mask pattern formed between the preliminary mask patterns in a plan view and spaced apart from the first upper mask pattern.
