Patent ID: 8680596

Claim:
A semiconductor device comprising: a semiconductor substrate; a first insulating film formed over the semiconductor substrate; a capacitor formed over the first insulating film, the capacitor being constructed from a lower electrode, a capacitor dielectric film made of a ferroelectric material, and an upper electrode; a second insulating film formed over the capacitor; a metal wiring formed over the second insulating film; a first capacitor protective insulating film formed at least on a side surface of the metal wiring; an insulating sidewall formed on the first capacitor protective insulating film on beside the metal wiring; a third insulating film formed over the metal wiring and the insulating sidewall, the third insulating film having a hole over the metal wiring; a conductive plug formed in the hole, the conductive plug being connected to the metal wiring; and a second capacitor protective insulating film formed over the third insulating film.
