  • Patent number: 7821065
    Abstract: An object of the present invention is to provide a semiconductor device having high operation characteristic and reliability. The measures taken are: A pixel capacitor is formed between an electrode comprising anodic capable material over an organic resin film, an anodic oxide film of the electrode and a pixel electrode above.

  • Patent number: 7803545
    Abstract: Heteroduplex band resolution is found to be improved by modifying the induced heteroduplex generator (IHG) molecule such that the identifier is spaced apart from the nucleotide position immediately adjacent to the site of the polymorphism which is to be genotyped. Unexpectedly, it is found that, when such modified IHG molecules are used, the resolution of the induced heteroduplexes is significantly improved.

  • Patent number: 7800114
    Abstract: Manufacture of TFTs corresponding to various circuits makes structures thereof complex, which involves a larger number of manufacturing steps. Such an increase in the number of the manufacturing steps leads to a higher manufacturing cost and a lower manufacturing yield. In the invention, a high concentration of impurities is doped by using as masks a tapered resist that is used for the manufacture of a tapered gate electrode, and the tapered gate electrode, and then the tapered gate electrode is etched in the perpendicular direction using the resist as a mask. A semiconductor layer under the thusly removed tapered portion of the gate electrode is doped with a low concentration of impurities.

    Abstract: A ground engaged vehicle includes a front portion and a rear portion joined by an articulation. The articulation rotates around a longitudinal axis. An engine drives a hydrostatic pump which drives four hydrostatic motors, each of the hydrostatic motors in operative engagement with one of four wheels. The wheels are on wheel mounts, each of the wheel mounts having a vertical axis around which one of the four wheels with one of the hydrostatic motors is turnable. A steering system turns the two wheels of the front portion in a first direction and the two wheels of the rear portion in an opposite direction. The steering system is powered by the hydrostatic pump. A pedal control system has a first pedal controlling driving the vehicle in a forward direction and a second pedal controlling driving the vehicle in a rearward direction.

  • Patent number: 7796240
    Abstract: The present invention provides an evaluation method for evaluating whether a light-emitting element material to be evaluated is suitable for a host material or a guest material. By carrying out a first step of measuring absorption intensity of a light-emitting element material and a second step of irradiating the light-emitting element material with light for a predetermined period of time, repeatedly; thereby a change in absorption intensity with time is evaluated so that whether the light-emitting material is suitable for a host material or a guest material can be distinguished. The light emitted to the light-emitting element material preferably has a wavelength component which is absorbed by a skeleton which contributes to excitation of the light-emitting element material.

    Abstract: To provide a manufacturing apparatus of a semiconductor device, which does not use a stepper in a manufacturing process in the case where mass production of semiconductor devices is carried out by using a large-sized substrate. A thin film formed over a substrate having an insulating surface is selectively irradiated with a laser beam through light control means, specifically through an electro-optical device to cause ablation; accordingly, the thin film is partially removed, thereby processing the thin film in a remaining region into a desired shape. The electro-optical device functions as a variable mask by inputting an electrical signal based on design CAD data of the semiconductor device.

  • Patent number: 7792176
    Abstract: A narrow-band laser device for exposure apparatus that allows to reduce damage to, and to hence extend the life of, optical elements such as chamber windows, output coupling mirrors or the like. A ring resonator is provided in an amplification stage laser of the narrow-band laser device for exposure apparatus that comprises an oscillation stage laser and an amplification stage laser. An OC, a high reflection mirror and a high reflection mirror are arranged to be offset, for instance, relative to a longitudinal direction axis of discharge electrodes. As a result, the beam width of laser light injected through the OC of the amplification stage laser becomes wider as the beam shifts inside the ring resonator, in each round trip within the ring resonator. The energy density of laser light in the optical elements of the amplification stage laser becomes reduced thereby, thus prolonging the life of the optical elements.
