A semiconductor device including a fin field effect transistor (fin-FET) includes active fins disposed on a substrate, isolation layers on both sides of the active fins, a gate structure formed to cross the active fins and the isolation layers, source/drain regions on the active fins on sidewalls of the gate structure, a first interlayer insulating layer on the isolation layers in contact with portions of the sidewalls of the gate structure and portions of surfaces of the source/drain regions, an etch stop layer configured to overlap the first interlayer insulating layer, the sidewalls of the gate structure, and the source/drain regions, and contact plugs formed to pass through the etch stop layer to contact the source/drain regions.

A barrier layer is formed in a portion of a thickness of sidewalls in a recess prior to formation of an interconnect structure in the recess. The barrier layer is formed in the portion of the thickness of the sidewalls by a plasma-based deposition operation, in which a precursor reacts with a silicon-rich surface to form the barrier layer. The barrier layer is formed in the portion of the thickness of the sidewalls in that the precursor consumes a portion of the silicon-rich surface of the sidewalls as a result of the plasma treatment. This enables the barrier layer to be formed in a manner in which the cross-sectional width reduction in the recess from the barrier layer is minimized while enabling the barrier layer to be used to promote adhesion in the recess.
