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 6):
The semiconductor memory device according to  claim 5 , wherein\n an upper surface of the third spacer is lower than an upper surface of the first spacer with respect to the upper surface of the substrate, an upper surface of the second spacer is lower than the upper surface of the third spacer with respect to the upper surface of the substrate, and each of the spacer structures further includes a fourth spacer on a sidewall of the first spacer and on the upper surface of the second spacer.
