    摘要: A trench is formed in an insulation film formed on top of a semiconductor substrate, and a barrier metal film is formed on the surface of the trench. After a copper or copper alloy film is formed on the barrier metal film, an oxygen absorption film in which a standard energy of formation of an oxidation reaction in a range from room temperature to 400° C. is negative, and in which an absolute value of the standard energy of formation is larger than that of the barrier metal film is formed, and the assembly is heated in a temperature range of 200 to 400° C. A semiconductor device can thereby be provided that has highly reliable wiring, in which the adhesion to the barrier metal film in the copper interface is enhanced, copper diffusion in the interface is suppressed, and electromigration and stress migration are prevented.

    摘要: Provided is a wiring of the Damascene structure for preventing the TDDB withstand voltage degradation and for keeping the planarity to prevent the degradation of a focus margin. A trench wiring (213) is formed in an interlayer insulating film, which is composed of a silicon carbide-nitride film (205), a SiOCH film (206) and a silicon oxide film (207) [(e)]. The silicon oxide film (207) is etched at a portion adjacent to the wiring of a polished surface by dry etching or wet etching [(f)]. A silicon carbide-nitride film (SiCN) (214) is formed as a Cu cap film [(g)]. An interlayer insulating film is further formed thereon to form a conductive plug, a trench wiring and so on.

    摘要: The present invention provides a semiconductor device which is capable of enhancing adhesion at an interface between a wire-protection film and copper, suppressing dispersion of copper at the interface to avoid electromigration and stress-inducing voids, and having a highly reliable wire. An interlayer insulating film, and a first etching-stopper film are formed on a semiconductor substrate on which a semiconductor device is fabricated. A first alloy-wire covered with a first barrier metal film is formed on the first etching-stopper film by a damascene process. The first alloy-wire is covered at an upper surface thereof with a first wire-protection film. The first wire-protection film covering an upper surface of the first alloy-wire contains at least one metal among metals contained in the first alloy-wire.
