Abstract:
A semiconductor memory device includes a substrate including active regions, word lines in the substrate and each extending in a first direction parallel to an upper surface of the substrate, bit line structures connected to the active regions, respectively, and each extending in a second direction crossing the first direction, and spacer structures on sidewalls of respective ones of the bit line structures. Each of the spacer structures includes a first spacer, a second spacer, and a third spacer. The second spacer is disposed between the first spacer and the third spacer and includes a void defined by an inner surface of the second spacer. A height of the second spacer is greater than a height of the void.

Claim (Index 15):
The method according to  claim 14 , further comprising:\n forming fence insulating patterns crossing the bit line structures, the forming the fence insulating patterns including defining contact regions by facing sidewalls of adjacent ones of the bit line structures and facing sidewalls of adjacent ones of the fence insulating patterns, the forming the contact plugs includes forming the contact plugs in lower portions of the contact regions, respectively, the removing the sacrificial spacer is performed after the forming the contact plugs in lower portions of the contact regions, respectively, and the sacrificial spacer is removed through the contact regions.
