Abstract: Provided is a semiconductor device with a wiring layer including a plurality of wiring lines extending in a first direction; a first insulating film stacked on the wiring layer that has a gap region between the plurality of wiring lines adjacent to each other in a second direction; and a second insulating film between the plurality of wiring lines and the first insulating film. Each wiring line includes a metal film and a barrier metal layer. The metal film includes an electrically conductive material including a first metal. The barrier metal layer partially covers surroundings of the metal film in a cross section orthogonal to the first direction and includes a material including a second metal. The second metal prevents diffusion of the first metal. The second insulating film includes an insulating material and covers a portion of the metal film. The insulating material prevents diffusion of the first metal.
