    Abstract: A memory device includes a substrate having first and second active patterns adjacent to each other and separated by a trench, the first and second active patterns including a first source/drain region; the second active pattern includes a second source/drain region. The second source/drain region includes first and second sidewall surfaces adjacent the first source/drain region and a connecting surface that connects the first and second sidewall surfaces. The second sidewall surface is set back from the first sidewall surface. An isolation layer is included in the trench and on the first sidewall surface. A bit line includes a contact part connected to the first source/drain region. A contact is coupled to the second source/drain region with a lower spacer between the contact and the contact part of the bit line, a landing pad on the contact, and a data storage element on the landing pad.

    Abstract: A semiconductor device includes a substrate having an active region defined by a device isolation layer and at least a gate trench linearly extending in a first direction to cross the active region, the active region having a gate area at a bottom of the gate trench and a junction area at a surface of the substrate. The device further may include a first conductive line filling the gate trench and extending in the first direction, the first conductive line having a buried gate structure on the gate area of the active region. The device also may include a junction including implanted dopants at the junction area of the active region, and a junction separator on the device isolation layer and defining the junction. The junction separator may be formed of an insulative material and have an etch resistance greater than that of the device isolation layer.
