ABSTRACT:
A semiconductor memory device includes a plurality of memory cells each including a transistor formed on a surface of a semiconductor substrate and having one terminal, and a capacitor formed on the semiconductor substrate and having first and second electrodes, with the first electrode being connected with one terminal of the transistor. The first electrode of the capacitor includes of a principal portion of either a generally rectangular cubic configuration or a generally cup-shaped configuration, a peripheral portion spaced from and surrounding a peripheral side wall of the principal portion and a bottom portion connecting an end of the principal portion with an end of the peripheral portion. On the other hand, the second electrode of the capacitor is includes of respective portions confronting the principal portion, the peripheral portion and the bottom portion of the first electrode.
