Abstract:
A method for fabricating a semiconductor device comprising the steps of:forming a first conducting film on a base substrate; forming a cap film on the first conducting film; patterning the cap film and the first conducting film to form pillar-shaped storage electrodes having top surfaces covered with the cap film; forming a capacitor dielectric film on the pillar-shaped storage electrodes; forming a second conducting film on the capacitor dielectric film; and etching the second conducting film until the capacitor dielectric film in regions overlapping the top surfaces of the pillar-shaped storage electrodes is exposed to form an opposed electrode of the second conducting film on outer sidewalls of the pillar-shaped storage electrodes interposing the capacitor dielectric film therebetween, the opposed electrode being formed between the adjoining storage electrodes.
