A semiconductor device includes a first interlayer insulating film; a conductive connection structure provided in the first interlayer insulating film; a second interlayer insulating film provided on the first interlayer insulating film; a wiring structure provided in the second interlayer insulating film and connected to the conductive connection structure; and an insertion liner interposed between an upper surface of the conductive connection structure and the wiring structure, the insertion liner including carbon.

Semiconductor device

A semiconductor device includes a substrate including an active region, a gate structure, source/drain regions, ones of the source/drain regions having an upper surface in which a recessed region is formed, a contact plug on the source/drain regions and extending in a direction substantially perpendicular to an upper surface of the substrate from an interior of the recessed region, a metal silicide film on an internal surface of the recessed region and including a first portion between a bottom surface of the recessed region and a lower surface of the contact plug and a second portion between a side wall of the recessed region and a side surface of the contact plug, and a metal layer connected to an upper portion of the metal silicide film and on a side surface of a region of the contact plug.

Semiconductor devices having reduced contact resistance

Semiconductor devices may have a first semiconductor element including first active regions that are doped with a first conductivity-type impurity and that are on a semiconductor substrate, a first gate structure between the first active regions, and first contacts connected to the first active regions, respectively; and a second semiconductor element including second active regions that are doped with a second conductivity-type impurity different from the first conductivity-type impurity and that are on the semiconductor substrate, a second gate structure between the second active regions, and second contacts connected to the second active regions, respectively, and having a second length greater than a first length of each of the first contacts in a first direction parallel to an upper surface of the semiconductor substrate.
