Abstract: An integrated circuit device may include a pair of line structures. Each line structure may include a pair of conductive lines extending over a substrate in a first horizontal direction and a pair of insulating capping patterns respectively covering the pair of conductive lines. The integrated circuit device may include a conductive plug between the pair of line structures and a metal silicide film contacting a top surface of the conductive plug between the pair of insulating capping patterns. The conductive plug may have a first width between the pair of conductive lines and a second width between the pair of insulating capping patterns, in a second horizontal direction perpendicular to the first horizontal direction, where the second width is greater than the first width.

Abstract: A semiconductor device includes: a substrate having active regions defined by a device isolation region; a conductive line extending in a direction on the active regions; insulating liners on both sidewalls of a lower portion of the conductive line that contacts with the active regions; spacers that are apart from the insulating liners in a direction perpendicular to a surface of the substrate and sequentially formed on both sidewalls of an upper portion of the conductive line; a blocking layer arranged at a spacing between a spacer located in the middle of the spacers and the insulating liners and in a recess portion recessed from one end of the spacer located in the middle of the spacers toward the conductive line; and conductive patterns arranged on the active regions on both sides of the spacers.
