Abstract

An integrated circuit (IC) device includes a lower electrode including a main portion having a sidewall with at least one step portion, and a top portion having a width less than that of the main portion in a lateral direction. An upper support pattern contacts the top portion of the lower electrode. The upper support pattern includes a seam portion. To manufacture an IC device, a mold pattern and an upper sacrificial support pattern through which a plurality of holes pass are formed on a substrate. A plurality of lower electrodes are formed inside the plurality of holes. A peripheral space is formed on the mold pattern. An enlarged peripheral space is formed by reducing a width and a height of the top portion. An upper support pattern is formed to fill the enlarged peripheral space.
