ABSTRACT:
In a semiconductor device including: an insulating film (6) formed over a substrate (1); a buried metal interconnect (10) formed in the insulating film (6); and a barrier metal film (A1) formed between the insulating film (6) and the metal interconnect (10), the barrier metal film (A1) includes a metal oxide film (7), a metal compound film (8) and a metal film (9) stacked in this order from a side in which the insulating film (6) exists to a side in which the metal interconnect (10) exists. Elastic modulus of the metal compound film (8) is larger than that of the metal oxide film (7).
