Abstract:
1. A method of manufacturing a semiconductor device including a capacitor including a pair of electrodes and a ferroelectric film with ferroelectricity sandwiched therebetween, the method comprising the steps of: (a) depositing the ferroelectric film on a first substrate; (b) forming the capacitor by grinding the ferroelectric film and forming the electrodes so that the electrodes are perpendicular to a direction of a polarization axis of the ferroelectric film; (c) forming a first interlayer insulating film covering a surface of the first substrate and the capacitor; (d) forming a transistor on a second substrate, the transistor including a gate electrode and a diffusion region; (e) forming a second interlayer insulating film covering a surface of the surface of the second substrate and the transistor; (f) flattening surfaces of the first and second interlayer insulating films by chemical mechanical polishing; (g) integrating the first and second substrates by joining the flattened surfaces of the first and second interlayer insulating film; and (h) removing the first substrate.
