摘要： 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.

摘要： Manufacturing processes for phase change memory have suffered from the problem of chalcogenide material being susceptible to delamination, since this material exhibits low adhesion to high melting point metals and silicon oxide films. Furthermore, chalcogenide material has low thermal stability and hence tends to sublime during the manufacturing process of phase change memory. According to the present invention, conductive or insulative adhesive layers are formed over and under the chalcogenide material layer to enhance its delamination strength. Further, a protective film made up of a nitride film is formed on the sidewalls of the chalcogenide material layer to prevent sublimation of the chalcogenide material layer.
