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 1):
A semiconductor memory device comprising:\n a substrate including active regions; word lines in the substrate, each of the word lines extending in a first direction parallel to an upper surface of the substrate; bit line structures connected to the active regions, respectively, each of the bit line structures extending in a second direction crossing the first direction; and spacer structures on sidewalls of respective ones of the bit line structures,\n each of the spacer structures including a first spacer, a second spacer, and a third spacer, \n the second spacer being disposed between the first spacer and the third spacer, the second spacer including a void, and a height of the second spacer being greater than a height of the void with respect to the upper surface of the substrate, the second spacer filling a bottom portion of a gap region defined by the first spacer and the third spacer.
