ABSTRACT:
For forming stacked capacitors, an opening is formed through at least one semiconductor material. A lower electrode material is patterned within the opening to form a plurality of lower electrodes within the opening. The stacked capacitors are formed with the lower electrodes within the opening by depositing a capacitor dielectric and an upper electrode within the opening. With such a relatively large opening, a capacitor dielectric of the stacked capacitors is deposited with a large thickness for improving reliability of the stacked capacitors.
