The reliability of wirings, each of which includes a main conductive film containing copper as a primary component, is improved. On an insulating film including the upper surface of a wiring serving as a lower layer wiring, an insulating film formed of a silicon carbonitride film having excellent barrier properties to copper is formed; on the insulating film, an insulating film formed of a silicon carbide film having excellent adhesiveness to a low dielectric constant material film is formed; on the insulating film, an insulating film formed of a low dielectric constant material as an interlayer insulating film is formed; and thereafter a wiring as an upper layer wiring is formed.

An object of the present invention is to provide a phase-change random access memory which hardly causes the peeling of a phase-change film in a production process. In the present invention, the surface of an insulating film around the phase-change film is positioned to a more substrate side than an interface between the insulating film and the phase-change film on the insulating film is.
