  • Publication number: 20240133918
    Abstract: In a method for obtaining the equivalent oxide thickness of a dielectric layer, a first semiconductor capacitor including a first silicon dioxide layer and a second semiconductor capacitor including a second silicon dioxide layer are provided and a modulation voltage is applied to the semiconductor capacitors to measure a first scanning capacitance microscopic signal and a second scanning capacitance microscopic signal. According to the equivalent oxide thicknesses of the silicon dioxide layers and the scanning capacitance microscopic signals, an impedance ratio is calculated. The modulation voltage is applied to a third semiconductor capacitor including a dielectric layer to measure a third scanning capacitance microscopic signal. Finally, the equivalent oxide thickness of the dielectric layer is obtained according to the equivalent oxide thickness of the first silicon dioxide layer, the first scanning capacitance microscopic signal, third scanning capacitance microscopic signal, and the impedance ratio.

  • Patent number: 8912483
    Abstract: A display measuring device for measuring a display, includes a photosensitive unit, a first rotation plane mirror, a second rotation plane mirror, a first lens module, a second lens module, and an optic reflecting unit. The first lens module projects a first incident image from the display to the first rotation plane mirror. The first rotation plane mirror reflects the projected first incident image from the first lens module to the optic reflecting unit. The second lens module projects a second incident image from the display to the second rotation plane mirror. The second rotation plane mirror reflects the projected second incident image from the second lens module to the optic reflecting unit. The optic reflecting unit reflects the reflected first incident image to the photosensitive unit, and reflects the reflected second incident image to the photosensitive unit.

  • Patent number: 8717677
    Abstract: An optical device is provided. The optical device comprises a substrate having a coating region and a non-coating region. A first film is on the coating region, wherein the first film has a band edge structure extending to a portion of the non-coating region with an angle between a surface of the band edge structure and a surface of the first film to diminish the attenuation of an incident light beam.

  • Patent number: 7751100
    Abstract: A scanning apparatus includes a housing with a flatbed. A loading glass is installed at the scan flatbed for loading a to-be-scanned document. A photoelectric sensing device is disposed in the housing for sensing the light signals corresponding to the to-be-scanned document to generate electric signals. The electric signals are transmitted through a flat cable to a motherboard. When the photoelectric sensing device shifts and the flat cable touches the bottom of the housing, the first adsorptive slice of the flat cable and the second adsorptive slice on the bottom of the housing adsorb each other. Therefore, the rubbing between the flat cable and the loading glass can be avoided and the quality of the scanning images can be improved.

  • Patent number: 7450276
    Abstract: A scanning apparatus includes a housing with a scan flatbed. A loading glass is installed at the scan flatbed of the housing for loading a to-be-scanned document. A photoelectric sensing device senses the light corresponding to the to-be-scanned document to generate electric signals. The electric signals are transmitted through a flat cable to a motherboard. The flat cable is designed to include a line peak so that the surface friction between the flat cable and the loading glass can be reduced to line friction. The flat cable can also be shifted near the sidewall of the housing and is inclined to the center of the housing so that the friction traces remained on the loading glass is outside the scan flatbed. Thus, the abrasion on the loading glass can be reduced and the quality of the scanning images can be improved.
