  • Publication number: 20070055480
    Abstract: A self-diagnosis system of a processor capable of realizing a sufficiently high processing ability for control tasks is provided without deteriorating reliability of safety controls even in complex diagnostic techniques. The self-diagnosis system is equipped with a diagnostic target area allocator for allocating a non-active area within a memory as a diagnosis-ready area, which is not used in a control task under execution by a main processor in an independent manner from the main processor; and a diagnostic executor for executing a diagnosis based upon a predetermined sequence in an independent manner from the main processor. In the self-diagnosis system, a diagnostic target area segmented from the diagnosis-ready area is selected, and a diagnosis of the selected diagnostic target area is carried out in each of diagnostic cycles by the diagnostic executor.

  • Patent number: 7173583
    Abstract: Side faces of anodes have a tapered incline that becomes broader toward a lower layer. Thus, an emissive element layer is smoothly formed on the anodes making it possible to prevent field contraction of the electric field. An EL display apparatus having long life and high yield is provided by preventing the emissive element layer from rupturing between an anode and a cathode and by preventing concentration of the electric field at an upper edge of the anode facing the cathode and localized deterioration in the emissive element layer.

  • Publication number: 20060282702
    Abstract: Processed results are received when processors make compatible computations on data of a common object. A computation command signal is generated and fed to the processors in response to a start signal from any one of the processors so that the processors can make computations with different operation timings. Then, the results of the computations made by the processors are compared with each other. Thus, apparatus capable of small size, high performance and safety at the same time can be achieved by the above construction using the processors.

  • Patent number: 7148545
    Abstract: A first semiconductor layer that makes a capacitance coupling with a gate electrode of a thin film transistor through a gate insulating layer and a second semiconductor layer that makes a capacitance coupling with a storage capacitor line of a storage capacitor through the gate insulating layer are formed separately. Also, the first semiconductor layer and the second semiconductor layer are connected by a metal wiring. The gate electrode of the thin film transistor makes capacitance coupling with the first semiconductor layer and the storage capacitor line of the storage capacitor makes capacitance coupling with the second semiconductor layer independently. Voltage are induced in the first semiconductor layer and the second semiconductor layer independently. Since there will be no big discrepancy in voltage in the gate insulating layer, the dielectric break down and the leakage can be prevented.

  • Patent number: 7078274
    Abstract: In an active matrix type display having built-in drivers, a metal layer is formed over a portion of a transparent substrate and a buffer layer is provided over both the region where the metal layer is formed and over the region where the metal layer is not formed. Above the buffer layer, a first polycrystalline silicon film is provided over the region where the metal layer is formed and a second polycrystalline silicon film is provided over the region where the metal layer is not formed. A buffer layer with sufficient thickness and thermal capacity can provide sufficient distance between the active layers and the lower metal layer to alleviate thermal leakage caused by the metal layer. A first polycrystalline silicon film and a second polycrystalline film each having a proper grain size can be obtained through laser annealing applied under the same conditions on an amorphous silicon film formed over the buffer layer.

  • Patent number: 7061017
    Abstract: For obtaining p-Si by irradiating a laser beam to an a-Si layer to polycrystallize, an energy level in a region to be irradiated by the laser beam is set such that a level at the rear area of the region along a scan direction of the laser beam is lower than that at the front area or the center area of the region. The energy level at the front area or the center area of the region is set such that it is substantially equal to or more than the upper limit energy level which maximizes a grain size of the p-Si obtained. Since an energy profile is set as described above, when the laser beam is scanned on the a-Si layer, an irradiated energy of the laser on the region is gradually lowered from the upper limit as the laser beam passes through, which allows the semiconductor layer to be annealed within an optimal energy level during the latter half of the annealing process.

  • Publication number: 20060103785
    Abstract: In a liquid crystal display device, a thickness of a liquid crystal layer in each pixel is adjusted based on a display color (red, green, and blue). For example, thicknesses of color filters corresponding to the display colors are varied based on the display color to set the thickness (cell gap) of the liquid crystal layer in each pixel to a predetermined value corresponding to a transmittance of the liquid crystal. A spacer provided to maintain the cell gap at a constant value is not provided in a region, among the plurality of display colors, having a large cell gap and the spacer is provided above the color filter or the like at a pixel region having smaller cell gap. With this structure, all spacers provided within a cell can substantially contribute to maintaining the gap.

  • Publication number: 20060103786
    Abstract: In a liquid crystal display device, a thickness of a liquid crystal layer in each pixel is adjusted according to a display color (red, green, and blue). For example, by changing the thickness of the color filter corresponding to the display color according to the display color, a thickness (cell gap) of the liquid crystal layer in each pixel is set to a predetermined value corresponding to the transmittance of light in the liquid crystal. In order to maintain the cell gap at a constant value, heights of spacers formed above the color filters are set to values different from each other according to the thickness of the liquid crystal layer which differs for each display color. With this structure, the spacers substantially contribute to maintaining the gap in the pixel regions of different display colors in which the spacers are formed.

  • Patent number: 7045818
    Abstract: In a fabrication process of a semiconductor device for use in a TFT liquid crystal display system, before the start of crystallizing amorphous silicon (a-Si), dehydrogenation annealing is carried out to not only decrease the density of hydrogen in the p-Si film (13) to 5×1020 atoms/cm3 at most but also to prevent crystallization of the a-Si film (13) being obstructed due to possible excessive hydrogen remaining in the film. With the p-Si film (13) covered with an interlayer insulation film (15) in the form of a plasma nitride film, annealing is then carried out in nitrogen atmosphere at a temperature of 350° C. to 400° C. for one to three hours, more preferably 400° C. for two hours. The result is that hydrogen atoms in the p-Si film (13) efficiently terminate dangling bonds of the film and hence do not become excessive, thus improving the electrical characteristics of the semiconductor device.
