摘要:
In a method for forming a silicon-on-insulator FET providing a contact to be given a fixed potential to a substrate, substrate-biasing between an SOI transistor and the silicon substrate is performed via a plug. As a result, the contact hole for the substrate-biasing does not need to pass through an insulating layer, a silicon layer, and an interlayer insulating layer. Therefore, the interlayer insulating layer can be made to have shallow depth. Ions can be implanted to the surface of the substrate via the contact hole for substrate biasing. As a result, contact holes for substrate-biasing can be formed without the contact holes for substrate-biasing causing an opening fault.

A method for removing thiophene and thiophene compounds from liquid fuel includes contacting the liquid fuel with an adsorbent which preferentially adsorbs the thiophene and thiophene compounds. The adsorption takes place at a selected temperature and pressure, thereby producing a non-adsorbed component and a thiophene/thiophene compound-rich adsorbed component. The adsorbent includes either a metal or a metal ion that is adapted to form π-complexation bonds with the thiophene and/or thiophene compounds, and the preferential adsorption occurs by π-complexation. A further method includes selective removal of aromatic compounds from a mixture of aromatic and aliphatic compounds.
摘要:
An oriented syndiotactic polystyrene-based film composed of an oriented film made of a syndiotactic styrene polymer and an adhesiveness-improving layer formed from a specific water-dispersible resin on at least one surface of the oriented film, which is excellent in the tight adhesion between the oriented film and the adhesiveness-improving layer, the adhesion between the adhesiveness-improving layer and an ink layer or laminate layer applied thereon, economical efficiency, recyclability, and environmental compatibility in production. It is particularly preferable that the film be produced by applying the aqueous dispersion of the water-dispersible resin on unstretched or uniaxially stretched film to form the adhesiveness-improving layer, stretching the obtained laminate uni- or bi-axially at least one time, and then heat-treating the resulting laminate.

The contact hole for substrate-biasing can be formed without causing an opening fault.
摘要:
A method of manufacturing a semiconductor device having self-aligned contact structure with side wall spacers and offset nitride films. The method includes forming the side wall spacers as having lower side wall spacers that are composed of silicon oxide films and that are in contact with lower sides of gate electrode side walls, and as having upper side wall spacers that are composed of silicon nitride films and that are in contact with upper sides of the gate electrodes side walls. A distance is thus formed between the device substrate and an interface between the silicon nitride film and the silicon oxide film. This suppresses the hot carrier phenomenon and the occurence of poor contact.

In a manufacturing method of a semiconductor device, a metallic gate electrode film, a protective film and an offset nitride film are formed on a semiconductor substrate to compose a stacked structure. An insulating film which covers the stacked structure is etched to expose the offset nitride film, and the exposed offset nitride film is etched to expose the protective film. The exposed protective film may be etched to expose the metallic gate electrode film under predetermined etching conditions. An etching rate of the protective film is greater than that of the metallic gate electrode film. The etching of the insulating film and the etching of the exposed offset nitride film may form a contact hole. Alternatively, a refractory metallic film may be formed on the exposed protective film in the contact hole, which is chemically reacted with the protective film to form a conductive film on the metallic gate electrode film. A conductive plug is formed in the contact hole.

A vehicle information display system includes a head-up display for reflecting an image on a windshield of a vehicle and displaying the image so that a driver recognizes the image as a virtual image. Information is collected for being displayed by the head-up display. A circumstance of the vehicle, a circumstance of surrounding of the vehicle, or a circumstance of the driver is detected. The collected information is classified in accordance with a detection result. Then, display contents of the head-up display are controlled in accordance with a classification result.

A roller bearing for rotatably supporting a rotating shaft of an internal combustion engine between a main body and a cap of the internal combustion engine. The roller bearing including: a plurality of rollers; a retainer which is cirumferentially splittable and supports the plurality of rollers; and an outer race which is cirumferentially splittable and forms a raceway surface for the plurality of rollers. The retainer is split into a plurality of retaining members. The outer race is split into a plurality of race plates. At least one of the race plates is provided with one of a projection and a cavity to be engaged with one of the main body and the cap to restrict a relative movement between the one of the race plates and the one of the cylinder head and the cap.

A first aspect of an oil distributing structure for an internal combustion engine includes a bearing support wall including a plurality of guide ribs which are radially mounted on a surface thereof. The guide ribs may be integrally formed, and extend around an upper half of the bearing, for collecting oil which is splashed onto, and flows down the wall surface. In a second aspect of an oil distributing structure for an internal combustion engine, a slanted edge portion, descending toward the bearing, is formed on the bearing support wall, and is disposed laterally of a lower portion of the bearing. The described structure is useful for collecting oil splashed onto a wall surface of a crankcase, and for supplying the collected oil to a bearing in an internal combustion engine of the type in which a crankshaft bearing is supplied with oil splashed from nearby gears.
