Abstract
A semiconductor device includes an active region defined by a device isolation layer, a pad layer on the device isolation layer and a first region of the active region, a first separation layer penetrating through the pad layer and extending in a first direction, a second separation layer penetrating through the pad layer and extending in a second direction, a word line below the second separation layer, extending in the second direction, and embedded in a substrate, a bit line extending in the first direction and connected to a second region of the active region, a contact structure on a side surface of the bit line and connected to the pad layer, and an data storage structure on the contact structure and connected to the contact structure. The first separation layer includes an airgap or a material having a dielectric constant less than a dielectric constant of silicon nitride.
