    Abstract: A semiconductor memory device includes word lines extending in a first direction on a semiconductor substrate, bit line structures crossing over the word lines and extending in a second direction intersecting the first direction, and contact pad structures between the word lines and between the bit line structures in plan view. A spacer structure extends between the bit line structures and the contact pad structures. The spacer structure includes a first air gap extending in the second direction along sidewalls of the bit line structures and a second air gap surrounding each of the contact pad structures and coupled to the first air gap.

    Abstract: An integrated circuit device may include a pair of line structures. Each line structure may include a pair of conductive lines extending over a substrate in a first horizontal direction and a pair of insulating capping patterns respectively covering the pair of conductive lines. The integrated circuit device may include a conductive plug between the pair of line structures and a metal silicide film contacting a top surface of the conductive plug between the pair of insulating capping patterns. The conductive plug may have a first width between the pair of conductive lines and a second width between the pair of insulating capping patterns, in a second horizontal direction perpendicular to the first horizontal direction, where the second width is greater than the first width.

    Abstract: An integrated circuit device may include a support pattern over a substrate, a lower electrode pattern and a dielectric structure over the substrate, and an upper electrode structure on the dielectric structure. The support pattern may include a first support structure extending in a vertical direction. The lower electrode pattern may be between the support pattern and the dielectric structure. The lower electrode pattern may include a first group of N (e.g., an integer of 4 or more) lower electrodes that are spaced apart from each other and may extend in the vertical direction to a first level above the substrate. The dielectric structure may include a first dielectric protrusion that extends in the vertical direction and surrounds the first support structure and the first group of N lower electrodes. The upper electrode structure may include a first upper electrode protrusion that surrounds the first dielectric protrusion.
