    Abstract: An integrated circuit semiconductor device includes lower electrodes on a substrate, and a support structure supporting the lower electrodes around the lower electrodes. The support structure includes a first support structure supporting lower portions of the lower electrodes, a second support structure apart from the first support structure in a vertical direction perpendicular to the substrate and supporting middle portions of the lower electrodes, and a third support structure apart from the second support structure in the vertical direction perpendicular to the substrate and supporting node portions of the lower electrodes. Each of the first support structure, the second support structure, and the third support structure includes a support pattern and additional holes formed through the support pattern. The support pattern extends in a horizontal direction parallel to the substrate and surrounds the lower electrodes. The support pattern includes holes through which the lower electrodes pass.
