    摘要: After an interlayer insulating film is deposited on a silicon substrate, a contact hole or contact holes is or are formed at a desired position(s) and, then, after a polysilicon layer is deposited and the contact hole(s) is (are) embedded, the surface of the polysilicon layer is flattened by chemical and mechanical polishing using at least one of piperazine or colloidal silica slurry, and a barrier metal film 4 and a highly dielectric thin film 5 are deposited and processed to a desired size. Finally, an Al/TiN film 6 adapted for the upper electrode is formed. The leak current of the thin film capacitor which is obtained according to this method can be greatly reduced.

    摘要: A thin film capacitor uses a dielectric film of high dielectric constant. A lower electrode is disposed on a contact, an interlayer insulating film is in contact with the lower electrode, a dielectric film of high dielectric constant covers the lower electrode, and an upper electrode covers the dielectric film. Thicknesses of the dielectric film at lower end portions of the lower electrode are thin but thick enough to make a leakage current value lower than a tolerable value thereof. At locations immediately below the lower electrode, the interlayer insulating film has portions whose thicknesses are larger than thicknesses of other portions thereof. The interlayer insulating film is such that, immediately below the regions of the dielectric film which are located at lower end portions of sides of the lower electrode and at which thicknesses of the dielectric film are very thin, the thicknesses of the interlayer insulating film are made larger than the rest thereof, or the dielectric film is such that lower end portions thereof are thin but thick enough to make a leakage current value lower than a tolerable value thereof. In this way, the occurrence of leakage current at the lower end portions of the lower electrode is suppressed.

    摘要: A method for fabricating a thin-film capacitor for a semiconductor integrated circuit device includes steps of forming a barrier metal layer, forming a dielectric film, forming an interlayer insulating film, exposing the dielectric film and forming an upper electrode. The thin-film capacitor is fabricated by successively depositing the dielectric film and the upper electrode on a lower electrode. The dielectric film is made of a material having a high permittivity such as SrTiO.sub.3. The interlayer insulating film is left at side portions of the lower electrode and the dielectric film. In one aspect of the invention, even if the high permittivity film becomes thin at the side and end portions of the lower electrode, the interlayer insulating film can suppress an increase in a leakage current. In another aspect of the invention, the high permittivity film and lower electrode may be etched successively and collectively and an upper electrode is deposited thereon. It is possible to suppress an occurrence of short-circuiting of the electrodes and an increase in the leakage current at the side portions of the high permittivity film.

    摘要: A protective layer in a ferroelectric integrated circuit contains small amounts of oxygen to protect ferroelectric oxide material against hydrogen degradation during the fabrication process. Typically, the protective layer is a hydrogen diffusion barrier layer formed to cover a thin film of ferroelectric oxide material. In one method, a small amount of oxygen is included in the sputter atmosphere during deposition of a hydrogen diffusion barrier or a metallized wiring layer. The oxygen forms oxides that inhibit diffusion of hydrogen towards the ferroelectric oxide material. The oxygen forms a concentration gradient so that the oxygen concentration in the interior of the protective layer is zero, and the oxygen concentration near the surfaces of the layer is about two weight percent.
