A first insulating hydrogen barrier film is filled between lower electrodes of
some ferroelectric capacitors arranged along one direction out of a word line direction
and a bit line direction among a plurality of ferroelectric capacitors included
in a ferroelectric memory of this invention. A common capacitor dielectric film
commonly used by the some ferroelectric capacitors arranged along the one direction
is formed on the lower electrodes of the some ferroelectric capacitors arranged
along the one direction and on the first insulating hydrogen barrier film. A common
upper electrode commonly used by the some ferroelectric capacitors arranged along
the one direction is formed on the common capacitor dielectric film. A second insulating
hydrogen barrier film is formed so as to cover the common upper electrode.
