    • A method of forming a device isolation region includes the steps of: forming a first dielectric film and an oxidation-resistant deposition film successively on a semiconductor substrate; forming a trench groove in the semiconductor substrate by successively processing the oxidation-resistant deposition film, the first dielectric film and the semiconductor substrate by anisotropic etching; forming a second dielectric film to cover at least an inner surface of the trench groove; depositing a third dielectric film in the trench groove so that the thickness of the third dielectric film buried in the trench groove is larger than a depth of the trench groove; planarizing a surface of the third dielectric film and an upper surface of the trench groove; and removing the oxidation-resistant deposition film and the first dielectric film to form the device isolation region, wherein a thermal treatment of the entire substrate is carried out to densify the third dielectric film and to oxidize an interface between the second dielectric film and the semiconductor substrate.

    • 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 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 includes respective portions confronting the principal portion, the peripheral portion and the bottom portion of the first electrode.
