    Abstract: A semiconductor device includes an active pattern on a substrate. A bit line structure is on the active pattern. A spacer structure is on a sidewall of the bit line structure. A lower contact plug directly contacts the spacer structure. The spacer structure includes a first spacer covering an upper sidewall of the lower contact plug and a second spacer covering a lower sidewall of the lower contact plug and a portion of a lower surface of the lower contact plug. The lower contact plug includes an extension portion covered by the first and second spacers and a protrusion portion protruding from the first and second spacers. A bottom surface of the protrusion portion is disposed at a level that is lower than or equal to a level of a bottom surface of the second spacer.

    Abstract: A semiconductor device includes an active pattern array including active patterns, an isolation pattern, gate structures, bit line structures, and lower and upper contact plugs. The isolation pattern covers sidewalls of the active patterns. The gate structures extend through upper portions of the active patterns and the isolation pattern in a first direction, and are spaced apart from each other in a second direction. The bit line structures are on central portions of the active patterns and the isolation pattern, extend in the second direction, and are spaced apart from each other in the first direction. The lower contact plugs are disposed on end portions of the active patterns. The upper contact plugs are disposed on the lower contact plugs. The active pattern array includes active pattern rows including the active patterns spaced apart from each other in the first direction.
