A ferroelectric capacitor includes a lower electrode, a ferroelectric film
provided over the lower electrode and having a perovskite-type structure
and an upper electrode provided over the ferroelectric film. The
ferroelectric film includes a first ferroelectric film part having a
first crystal system and formed along at least one interface with at
least one of the lower electrode and the upper electrode and a second
ferroelectric film part having a second crystal system that is different
from the first crystal system.
