An embodiment of the present invention is a method of fabricating a semiconductor
device. The method comprises forming a film of bottom electrode material entirely
over the dielectric film; etching the bottom electrode film to partially define
a sidewall of each of bottom electrodes; forming a film of ferroelectric material
on the remainder of the bottom electrode film and the exposed surface of the dielectric
film; forming a film of top electrode material on the ferroelectric film; and etching
the top electrode film, the ferroelectric film and the remainder of the bottom
electrode film until the surface of the dielectric film is exposed to completely
define the sidewall of each of the bottom electrodes.
