    摘要: Disclosed is a semiconductor device including a substrate including first and second active regions, a device isolation layer on the substrate and defining first and second active patterns, first and second gate electrodes running across the first and second active regions and aligned with each other, first and second source/drain patterns on the first and second active patterns, a first active contact connecting the first and second source/drain patterns to each other, and a gate cutting pattern between the first and second gate electrodes. An upper portion of the first active contact includes first and second upper dielectric patterns. The first active contact has a minimum width at a portion between the first and second upper dielectric patterns. A minimum width of the gate cutting pattern is a second width. A ratio of the first width to the second width is in a range of 0.8 to 1.2.

    摘要: A semiconductor device includes a semiconductor substrate, a plurality of gate structures which are spaced apart from each other in a first horizontal direction on the semiconductor substrate and extend in a second horizontal direction perpendicular to the first horizontal direction, and a single diffusion brake which extends in the second horizontal direction between the plurality of gate structures and is located in a first trench having a first depth in a vertical direction. The single diffusion brake includes a lower insulating material film conformally disposed on a side wall of the first trench, an insulating liner extending onto upper surfaces of the plurality of gate structures along an inner wall of the lower insulating material film, and an upper insulating material film disposed on the insulating liner and filling the inside of the first trench.
