Abstract
A semiconductor device includes a plurality of wiring structures spaced apart from each other, and an insulating interlayer structure. Each of the wiring structures includes a metal pattern and a barrier pattern covering a sidewall, a bottom surface, and an edge portion of a top surface of the metal pattern and not covering a central portion of the top surface of the metal pattern. The insulating interlayer structure contains the wiring structures therein, and has an air gap between the wiring structures.
