Patent ID: 7507621

Claim:
A method for manufacturing a semiconductor device, comprising: forming a first insulating film on a semiconductor substrate; forming a capacitor in which a lower electrode, a capacitor dielectric film made of ferroelectric material and an upper electrode are laminated in this order on the first insulating film; forming a second insulating film covering the capacitor; forming a first metal interconnect on the second insulating film; forming a silicon nitride film as the first capacitor protect insulating film on the metal interconnect by a catalytic CVD method; forming an interlayer insulating film on the first capacitor protect insulating film; forming a silicon nitride film on the interlayer insulating film as a second capacitor protect insulating film by the catalytic CVD method; forming a third insulating film on the second capacitor protect insulating film; forming an glue film on the third insulating film; and forming a second metal interconnect on the glue film.
