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 8):
The semiconductor memory device according to  claim 7 , further comprising:\n fence insulating patterns between each of the contact plugs, wherein the second spacer includes first portions and second portions, the first portions of the second spacer are between each of the contact plugs and each of the bit line structures, the second portions of the second spacer are between the each of the fence insulating patterns and each of the bit line structures, and the separation layer contacts at least one of the first portions of the second spacer or the second portions of the second spacer.
