Patent ID: 7800112

Claim:
A semiconductor device comprising: a semiconductor substrate; and an MIM capacitor, the MIM capacitor comprising: a first insulation film provided on the semiconductor substrate; a first conductive film made of a material of which a polishing rate is lower than the polishing rate of the first insulation film and embedded in a predetermined region of the first insulation film; a plurality of grooves which penetrate through the first conductive film and reach the first insulation film; metallic wirings embedded in the respective grooves so as to be in contact with the first conductive film; a dielectric film provided on the metallic wirings and the first conductive film; and a second conductive film provided on the dielectric film, wherein the metallic wirings and the first conductive film constitute a lower electrode of the MIM capacitor, the dielectric film constitutes a dielectric layer of the MIM capacitor, and the second conductive film constitutes an upper electrode of the MIM capacitor.
