Abstract:
After forming an interlayer insulating film (14) covering a ferroelectric capacitor, a hydrogen diffusion preventing film (18), an etching stopper (19) and an interlayer insulating film (20) are formed. Then, a wiring having a tantalum nitride (TaN) film (21) (barrier metal film) and a copper (Cu) film (22) is formed in the interlayer insulating film (20) by a single damascene method. Thereafter, a wiring having a copper film (29) and a wiring having a copper film (36) and the like are formed by a dual damascene method.
