  • Patent number: 8101018
    Abstract: In a method for fabricating a semiconductor device and an apparatus for inspecting a semiconductor, laser processing is performed at different laser powers at different positions on a monitor substrate from a plurality of substrates having undergone an SPC step, to form polycrystalline silicon film over the entire area of the substrate. Thereafter, in an optimum power inspection/extraction step, the polycrystalline silicon film formed with varying film quality on the monitor substrate is inspected on inspection equipment to determine the optimum laser power. Then, in a laser processing step, the surface of the subsequent substrates having undergone the SPC step is irradiated with laser at the optimum laser power. Thus, high-quality polycrystalline silicon film is formed over the entire area of the substrate.

  • Patent number: 6587161
    Abstract: A pixel substrate has a plurality of scanning lines and a plurality of reference signal lines which are arranged parallel with each other. A counter substrate includes a plurality of signal lines. Moreover, the pixel substrate has a connecting line for connecting the plurality of the reference signal lines to each other. The connecting line is provided in each of two regions outside of two sides among the peripheral sides of a region where a plurality of pixel electrodes are formed, the two sides being perpendicular to the reference signal lines. In this structure, a reference signal is input from both ends of the reference signal line. It is therefore possible to provide a liquid crystal display device which reduces the occurrence of a short circuit between the lines on the substrate and decreases the signal delay due to the load capacitance.

  • Patent number: 6441879
    Abstract: A liquid crystal display device is provided with a switching element in neighborhoods of crossing points of a gate wiring and a data wiring. An interlayer insulating film is provided on the switching element. A pixel electrode connected with the switching element is provided on the interlayer insulating film. Moreover, a spacer for keeping a thickness of a liquid crystal layer constant is disposed in the liquid crystal layer and in a sealing member for sealing the liquid crystal layer. Materials of the interlayer insulating film and spacers are optimized. This configuration prevents degradation of a defective ratio and reliability due to the spacer disposed in the liquid crystal layer sinking into the interlayer insulating film.
