Abstract:
A semiconductor device comprising:a capacitor including a lower electrode formed over a semiconductor substrate, a dielectric film formed of ferroelectric material or high-dielectric material, and an upper electrode; a first capacitor protection film formed above the capacitor; a first insulating film formed above the first capacitor protection film; a first wiring formed above the first insulating film; a second insulating film formed above the first wiring and first insulating film; a second wiring formed above the second insulating film; a third insulating film formed above the second wiring and the second insulating film; and at least one of a second capacitor protection film and a third capacitor protection film, the second capacitor protection film formed above the first wiring to cover the capacitor and formed under the second insulating film, and the third capacitor protection film formed above the third insulating film and above at least the upper electrode of the capacitor and set to an earth potential.
