Patent ID: 8614104

Claim:
A method for manufacturing a semiconductor device, comprising: forming a ferroelectric capacitor including a bottom electrode, a ferroelectric film and a top electrode, over a semiconductor substrate; forming an interlayer insulating film covering the ferroelectric capacitor; forming a contact hole reaching the top electrode in the interlayer insulating film; and forming a wiring electrically connected to the top electrode through the contact hole on the interlayer insulating film, wherein forming the top electrode comprises: forming a first conductive oxide film having a first composition ratio of oxygen; forming a second conductive oxide film on the first conductive oxide film, a second composition ratio of oxygen of the second conductive oxide film being higher than the first composition ratio of oxygen; and forming a cap film composed of a noble metal having less catalytic action than Pt (platinum) and having a thickness of 150 nm or less on the second conductive oxide film.
