Abstract
A semiconductor device includes a first conductive pattern on a substrate, an insulating diffusion barrier layer conformally covering a surface of the first conductive pattern, the insulation diffusion barrier layer exposed by an air gap region adjacent to a sidewall of the first conductive pattern, and a second conductive pattern on the first conductive pattern, the second conductive pattern penetrating the insulating diffusion barrier layer so as to be in contact with the first conductive pattern.
