Abstract:
1. A semiconductor device manufacturing method having a ferroelectric capacitor having a ferroelectric film comprising: forming a first interlayer insulating film above a semiconductor substrate; forming an anti-oxidation film above the first interlayer insulating film; forming the ferroelectric capacitor above the anti-oxidation film, the anti-oxidation film being provided under the entire bottom surface of the ferroelectric capacitor; forming a first moisture-resistant insulating film on the ferroelectric capacitor; forming a second interlayer insulating film having a multilayer structure over the first and second moisture-resistant insulating films; forming a dummy contact hole in the second interlayer insulating film; forming a contact hole in the second interlayer insulating film and the second moisture-resistant insulating film; and forming a dummy plug in the dummy contact hole filling a conductive material and a plug for electrical connection filling the conductive material in the contact hole.
