Patent ID: 8169051

Claim:
A semiconductor device, comprising: a semiconductor substrate; an insulating film formed over the semiconductor substrate; a first conductive plug formed in the insulating film; a second conductive plug formed in the insulating film; a capacitor element comprising a capacitor lower electrode connected to one end of the first conductive plug and formed on the insulating film, a dielectric film formed on an upper surface and side surfaces of the capacitor lower electrode, and a capacitor upper electrode formed on the dielectric film, the capacitor lower electrode comprising a first barrier film, the capacitor upper electrode comprising a second barrier metal film that is wider than the capacitor lower electrode; a wiring connected to one end of the second conductive plug and formed on the insulating film, the wiring comprising a first layer and a second layer formed on the first layer, the first layer comprising the first barrier metal film, the second layer comprising the second barrier metal film; a fuse formed in the insulating film off to a side of the capacitor element; and a protection pattern that covers at least a port of the fuse, the protection pattern comprising a conductive film that is same as that of the capacitor lower electrode.
