Abstract:
A semiconductor device, comprising:a semiconductor substrate;a transistor having a source/drain region and a gate electrode formed on said semiconductor substrate;a capacitor having an upper capacitor electrode, a lower capacitor electrode, and a metallic oxide dielectric disposed between said upper capacitor electrode and said lower capacitor electrode;a capacitor cover insulating film formed over said capacitor; anda first metal wiring formed over said capacitor cover insulating film;a first composite film having a first adhesive metal film and a first metal nitride barrier film disposed at an insulating film boundary between said capacitor cover insulating film and said first metal wiring and disposed at a transistor boundary which electrically connects said transistor to said first metal wiring; anda second metal nitride barrier film formed at a capacitor boundary between said capacitor and said metal wiring, wherein said first adhesive metal film is not disposed at said capacitor boundary.
