    Abstract: A wiring structure includes first to third metal patterns on a substrate. The first metal pattern extends in a second direction and has a first width in a third direction. The second metal pattern extends in the third direction to cross the first metal pattern and have a second width in the second direction. The third metal pattern is connected to the first and second metal patterns at an area where the first and second metal patterns cross each other, and has a substantially rectangular shape with concave portions in each quadrant. The third metal pattern has a third width defined as a minimum distance between opposite ones of the concave portions in a fourth direction having an acute angle to the second and third directions, which is less or equal to than a smaller of the first and second widths.

    Abstract: A semiconductor device includes a substrate including active regions extending in a first direction; a device isolation layer surrounding the active regions on the substrate; gate structures intersecting the active regions and extending on the substrate in a second direction; source/drain regions on the active regions; contact plugs connected to the source/drain regions, respectively; a vertical buried structure penetrating through at least a portion of the device isolation layer, and in contact with the contact plugs; a vertical insulating layer covering at least a portion of side surfaces of the vertical buried structure; a horizontal buried structure below the vertical buried structure; a first conductive barrier covering at least a portion of an upper surface and side surfaces of the horizontal buried structure; and a metal-semiconductor compound pattern between the vertical buried structure and the first conductive barrier, wherein the vertical buried structure is between source/drain regions.

    Abstract: A semiconductor device includes a substrate including a plurality of active patterns and a bit line intersecting at least one of the plurality of active patterns on the substrate and extending in a first direction. The bit line includes a first conductive pattern extending in the first direction, a bit line capping pattern extending in the first direction on the first conductive pattern, and a graphene pattern extending in the first direction between the first conductive pattern and the bit line capping pattern. The first conductive pattern may include ruthenium (Ru). The semiconductor device may also include one or more bit line contacts arranged in the first direction under the bit line, the one or more bit line contacts electrically connected to a respective one of the plurality of active patterns.
