| 摘要 |
A semiconductor device according to an aspect of the present invention comprises a semiconductor substrate, a ferroelectric capacitor, a protective film and an auxiliary capacitor. The ferroelectric capacitor is provided above the semiconductor substrate and comprises an upper electrode, a lower electrode and a ferroelectric film interposed between the upper and lower electrodes. The protective film is formed, covering the ferroelectric capacitor. The auxiliary capacitor is provided in a circuit section peripheral to the ferroelectric capacitor and uses the protective film as capacitor insulating film.
