    Abstract: A semiconductor device includes circuit elements on a first substrate; gate electrodes on a second substrate and stacked to be apart from each other in a first direction; sacrificial insulating layers on a lower through-insulating layer penetrating the second substrate, stacked to be spaced apart from each other in the first direction, and having side surfaces opposing the gate electrodes; channel structures penetrating the gate electrodes, extending vertically on the second substrate, and including a channel layer; a first separation pattern penetrating the gate electrodes and including a first barrier pattern and a first pattern portion extending from the first barrier pattern in a second direction; and a second separation pattern penetrating the gate electrodes, disposed to be parallel to the first separation pattern, and extending in the second direction. Some of the side surfaces of the sacrificial insulating layers may overlap the first barrier pattern in a third direction.

    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, a first metal interconnection provided on a first region of the substrate, and a second metal interconnection provided on a second region of the substrate. A width of the second metal interconnection is greater than a width of the first metal interconnection. The first metal interconnection includes a metal pattern. The second metal interconnection includes a lower metal pattern having a concave surface at its top, an upper metal pattern disposed on the concave surface at the top of the lower metal pattern, and a first barrier pattern interposed between the lower metal pattern and the upper metal pattern. The metal interconnections are formed by a damascene process including deposition, reflow, metal implantation, and planarization processes.

    Abstract: A semiconductor device includes gate electrodes stacked and spaced apart from each other in a first direction perpendicular to an upper surface of a substrate; interlayer insulating layers alternately stacked with the gate electrodes on the substrate; channel structures extending through the gate electrodes; and a separation region extending through the gate electrodes in the first direction and extending in a second direction perpendicular to the first direction, wherein each of the gate electrodes comprises a first conductive layer and a second conductive layer sequentially stacked, the second conductive layer including a metal nitride, and wherein the first conductive layer and the second conductive layer are each in physical contact with the separation region.
