Semiconductor device comprising a capacitor and method of manufacturing the same

摘要

There is provided a semiconductor device which comprises a capacitor including a lower electrode, a dielectric film, and an upper electrode, a first protection film formed on the capacitor, a first wiring formed on the first protection film, a first insulating film formed on the first wiring, a second wiring formed on the first insulating film, a second insulating film formed on the second wiring, and at least one of a second protection film formed between the first insulating film and the first wiring to cover at least the capacitor and a third protection film formed on the second insulating film to cover the capacitor and set to an earth potential. Accordingly, the degradation of the ferroelectric capacitor formed under the multi-layered wiring structure can be suppressed.
