    Abstract: A semiconductor device may include contact plug structures on a substrate, and an insulation structure filling a space between the contact plug structures to insulate the contact plug structures from each other. The contact plug structures may be spaced apart from each other in a first direction. The insulation structure may include a first insulation pattern and a second insulation pattern. The second insulation pattern may include an insulation material having an etch selectivity with respect to silicon oxide. The first insulation pattern may contact a portion of sidewalls of the second insulation pattern and a portion of sidewalls of the contact plug structure. The first insulation pattern may include a material having a band gap higher than a band gap of the second insulation pattern.

    Abstract: A semiconductor memory device includes an active pattern on a substrate and at least partially surrounded by a device isolation pattern, a bit line that extends on a center portion of the active pattern in a first direction that is parallel to a bottom surface of the substrate, and a bit line contact between the bit line and the active pattern. The bit line contact includes a metallic material. A width of the bit line contact at a first level and in a second direction is greater than a width of a bottom surface of the bit line contact in the second direction. The second direction intersects the first direction. The first level is between a top surface of the device isolation pattern and the substrate.
