Abstract: An integrated circuit memory device is formed by forming an interlevel insulating layer on a substrate. A plurality of storage node contact holes are formed in the interlayer insulating layer and are arranged in a pattern. A plurality of contact plugs are formed in the plurality of storage node contact holes, respectively. A material layer is formed on the interlevel insulating layer that has a plurality of landing pad holes that expose the plurality of contact plugs, respectively, the plurality of landing pad holes are arranged in a pattern that is offset with respect to the pattern of the storage node contact holes. A plurality of landing pads are formed in the plurality of landing pad holes and are connected to the plurality of contact plugs, respectively. A plurality of storage nodes are formed that are connected to the plurality of landing pads, respectively.
