Abstract:
1. A semiconductor device comprising: an insulating film; a lower insulating film formed beneath the insulating film; a lower interconnect formed on the lower insulating film; an interconnect made of a first conductive film and a second conductive film that are stacked in sequence from the interconnect underside on the insulating film; the lower interconnect made of the first conductive film and the second conductive film that are stacked in sequence from the lower interconnect underside on the lower insulating film; on the insulating film, a capacitor composed of: a lower capacitor electrode made of the first conductive film; a dielectric film formed on the lower capacitor electrode; and an upper capacitor electrode made of the second conductive film and formed on the dielectric film, wherein each of the lower capacitor electrode, the dielectric film, and the upper capacitor electrode has a same pattern; lower contacts are formed in the insulating film on a bottom surface of the lower capacitor electrode, the lower contacts being connected to the lower capacitor electrode; and the lower contacts are connected to the lower interconnect.
