Abstract: A semiconductor device may include a substrate including a cell region and a peripheral region, bit lines on the cell region and extending in a first direction parallel to a top surface of the substrate, a lower capping pattern on a top surface of each of the bit lines, a bit line spacer on a side surface of each of the bit lines and extending to a side surface of the lower capping pattern, and a respective upper capping pattern on a top surface of the lower capping pattern. The respective upper capping pattern is on at least a portion of a top surface of the bit line spacer.

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: Semiconductor devices, and methods for forming the same, include forming a first wiring film and an etching buffer film in a cell array region and a peripheral circuit region of a substrate, and forming a contact hole by selectively etching the etching buffer film and the first wiring film so as to expose an active region of the cell array region and at least a part of a field isolation region adjacent thereto. A bit line contact is formed in the contact hole to be in contact with the active region, and a second wiring film is formed over the substrate. By patterning the second wiring film, the bit line contact, the etching buffer film, and the first wiring film, a bit line is formed in the cell array region and a peripheral gate is formed in the peripheral circuit region.
