摘要：
Disclosed is a semiconductor device comprising a semiconductor substrate, a first insulating film formed above the semiconductor substrate, Cu wiring buried in the first insulating film, a second insulating film formed above the Cu wiring, and a discontinuous film made of at least one metal selected from the group consisting of Ti, Al, W, Pd, Sn, Ni, Mg and Zn, or a metal oxide thereof and interposed at an interface between the Cu wiring and the second insulating film.
