Abstract

Semiconductor devices and methods of fabricating the same are provided. The semiconductor device may include interconnections extending in a first direction on a substrate and spaced apart from each other in a second direction perpendicular to the first direction, barrier dielectric patterns disposed on top surfaces of the interconnections, respectively, and an upper interlayer dielectric layer disposed on the interconnection. Respective air gaps are disposed between adjacent ones of the interconnections.
