摘要:
A semiconductor disk wherein a flash memory into which data is rewritten in block units is employed as a storage medium, said a semiconductor disk comprises a data memory in which file data are stored, a substitutive memory which substitutes for blocks of errors in the data memory, an error memory in which error information of the data memory are stored, and a memory controller which reads data out of, writes data into and erases data from the data memory, the substitutive memory and the error memory. Since the write errors of the flash memory can be remedied, the service life of the semiconductor disk can be increased.

A fine substrate contact electrode (bump) made of a refractory metal having low resistance and sufficient mechanical strength is fabricated on a wiring substrate with a polyimide resin film serving as an electrically insulating layer. It is not the entire surface of the contact electrode that is covered with a high-resistance oxide film since the top surface of the refractory metal such as tungsten is covered with an oxidation-resistant metal film. The substrate contact electrode has a sufficient mechanical strength since the side of the tungsten bump is surrounded by a side wall reinforcement film even where the tungsten formed by the blanket chemical vapor deposition method is polycrystalline. Since the polyimide film is previously embedded before the substrate contact electrode is fabricated, the electrode can be formed on the polyimide film having a desired thickness on the entire substrate surface.

摘要:
An outer end portion of a webbing is guided in the longitudinal direction of the vehicle, and a tongue plate provided on said outer end portion is engaged with a buckle device secured to the rear portion of a roof side, whereby the webbing is fastened to an occupant. A release plate movable a certain distance with respect to the tongue plate is moved forwards in the vehicle by drive means, whereby the tongue plate is moved forwards in the vehicle after the tongue plate is disengaged from the buckle device, so that the webbing can be separated from the occupant to automatically unfasten the webbing from the occupant.
摘要:
A membrane for reverse osmosis comprising a porous base and a thin high polymer film attached to the porous base. The high polymer film includes at least one layer of radical polymer of nitrogen contained monomer and alkyl metal and at least one layer of polymer of nitrogen contained monomer which are alternately laminated on the porous base. The membrane is manufactured by combining the step of introducing nitrogen containing monomer, alkyl metal and the inert carrier gas into a plasma created by glow discharge to cause a radical polymerization reaction between nitrogen containing monomer and alkyl metal on the porous base disposed within the plasma, and the step of introducing in the plasma a nitrogen containing monomer and an inert carrier gas to cause polymerization of nitrogen containing monomer on the porous base.
摘要:
The present invention makes it possible to lower the on resistance of a semiconductor element without hindering the function of a diffusion prevention film in a semiconductor device having the semiconductor element that uses a wire in a wiring layer as a gate electrode and has a gate insulation film in an identical layer to the diffusion prevention film. A first wire and a gate electrode are embedded into the surface layer of an insulation layer comprising a first wiring layer. A diffusion prevention film is formed between the first wiring layer and a second wiring layer. A gate insulation film is formed by: forming a recess over the upper face of the diffusion prevention film in the region overlapping with the gate electrode and around the region; and thinning the part.

A method for manufacturing a semiconductor apparatus includes forming a semiconductor device on a principal surface of a substrate, in which the semiconductor device includes an interconnect layer, forming a buffer film which covers the semiconductor device and prevents diffusion of a magnetic material, and forming a magnetic shielding film which covers the buffer film and includes the magnetic material.
摘要:
A semiconductor device has a capacitive structure formed by sequentially layering, on a wiring or conductive plug, a lower electrode, a capacitive insulation film, and an upper electrode. The semiconductor device has, as the capacitive structure, a thin-film capacitor having a lower electrode structure composed of an amorphous or microcrystalline film or a laminate of these films formed on a polycrystalline film.
