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 18):
The method according to  claim 17 , further comprising:\n forming fence insulating patterns on the substrate, the fence insulating patterns crossing the bit line structures, wherein the separation region exposes at least one of, first portions of the sacrificial spacer between each of the contact plugs and each of the bit line structures, and second portions of the sacrificial spacer between each of the fence insulating patterns and each of the bit line structures.
