Patent ID: 7803640

Claim:
A semiconductor device, comprising: a first interlayer insulation film formed over a substrate; a ferroelectric capacitor formed over the first interlayer insulation film; a second interlayer insulation film formed on the first interlayer insulation film so as to cover the ferroelectric capacitor, wherein the ferroelectric capacitor includes a lower electrode, a ferroelectric film formed on the lower electrode, an upper electrode formed on the ferroelectric film in contact therewith, and a polish-resistant film formed on the upper electrode, a top surface of the second interlayer insulation film being coincident to a top surface of the polish-resistant film in the part covering the ferroelectric film, and the top surface of the second interlayer insulation film causing dishing with a depth of 20% or more with regard to a film thickness of the second interlayer insulation film.
