    Abstract: A semiconductor device includes a first active structure on a substrate including a first epitaxial pattern, a second epitaxial pattern and a first channel pattern between the first epitaxial pattern and the second epitaxial pattern, the first channel pattern including at least one channel pattern stacked on the substrate. A first gate structure is disposed on top and bottom surfaces of the first channel pattern. A second active structure on the substrate and includes the second epitaxial pattern, a third epitaxial pattern and a second channel pattern between the second epitaxial pattern and the third epitaxial pattern in the first direction. The second channel pattern includes at least one channel pattern stacked on the substrate. The number of stacked second channel patterns is greater than the number of stacked first channel patterns. A second gate structure is disposed on top and bottom surfaces of the second channel pattern.

    Abstract: A semiconductor device includes a substrate having cell areas and power areas that are alternately arranged in a second direction. Gate structures extend in the second direction. The gate structures are spaced apart from each other in a first direction perpendicular to the second direction. Junction layers are arranged at both sides of each gate structure. The junction layers are arranged in the second direction such that each of the junction layer has a flat portion that is proximate to the power area. Cutting patterns are arranged in the power areas. The cutting patterns extend in the first direction such that each of the gate structures and each of the junction layers in neighboring cell areas are separated from each other by the cutting pattern.

    Abstract: A semiconductor device is provided including a substrate, a first gate structure, a first contact plug and a power rail. The substrate includes first and second cell regions extending in a first direction, and a power rail region connected to each of opposite ends of the first and second cell regions in a second direction. The first gate structure extends in the second direction from a boundary area between the first and second cell regions to the power rail region. The first contact plug is formed on the power rail region, and contacts an upper surface of the first gate structure. The power rail extends in the first direction on the power rail region, and is electrically connected to the first contact plug. The power rail supplies a turn-off signal to the first gate structure through the first contact plug to electrically insulate the first and second cell regions.
