Patent ID: 7898012

Claim:
A semiconductor device, comprising: a semiconductor substrate; a transistor formed on the semiconductor substrate, the transistor including a gate electrode and a diffusion region; a first interlayer insulating film covering the semiconductor substrate and the transistor; a second interlayer insulating film formed on the first interlayer insulating film; and a capacitor formed in the second interlayer insulating film, the capacitor including a pair of electrodes and a ferroelectric film sandwiched therebetween, wherein the electrodes are provided perpendicular to a direction of a polarization axis of the ferroelectric film, the electrodes are provided on corresponding opposing (001) crystallographic surfaces of the ferroelectric film, the corresponding opposing (001) crystallographic surfaces being parallel to a direction of growth of the ferroelectric film; the ferroelectric film comprises PZT or a material formed by adding La, Ca, Sr or Nb to PZT; and wherein a top surface of the ferroelectric film is a (100) crystallographic surface.
