Abstract:
1. A method of fabricating a semiconductor device having a plurality of conductive regions formed through a dielectric film that has a surface, comprising the steps of: forming a film of bottom electrode material entirely over said surface of said dielectric film; partially removing said bottom electrode film, until said surface of said dielectric film is exposed, to partially define a sidewall of each of bottom electrodes, which are to be formed on said plurality of conductive regions, respectively; forming a film of ferroelectric material on the remainder of said bottom electrode film and said exposed surface of said dielectric film; forming a film of top electrode material on said ferroelectric film; and partially removing said top electrode film, said ferroelectric film and the remainder of said bottom electrode film, until said surface of said dielectric film is exposed, to completely define said sidewall of each of said bottom electrodes.
