  • Patent number: 7519448
    Abstract: A light source emits light toward a semiconductor wafer, and a light receiving sensor detects light passing a peripheral edge of the semiconductor wafer. Each coordinates of the peripheral edge of the semiconductor wafer is obtained from a result of the detection. Further, a center of the semiconductor wafer is obtained from a group of the coordinates. Then, an illumination device emits light toward the peripheral edge of the semiconductor wafer and an optical camera detects light reflected from the peripheral edge of the semiconductor wafer. A position of a “V”-shaped notch formed on the peripheral edge of the semiconductor wafer is obtained from a result of the detection. A handling position of the semiconductor wafer is determined based on the center of the semiconductor wafer and the position of the “V”-shaped notch.

  • Patent number: 7519142
    Abstract: A reconstruction process for processing pixel data for tomographic volume image data uses a concise reconstruction algorithm based on an assumption that an axis of X-ray emission axis always exists on a plane orthogonal to an axis of revolution of an X-ray tube and an FPD. In time of the reconstruction process, a corrected parameter is applied to the reconstruction algorithm for correcting a mechanical displacement occurring between the axis of revolution of the X-ray tube and FPD and the axis of X-ray emission. Thus, errors due to the mechanical displacement may be avoided by a simple data processing of setting the corrected parameter to the reconstruction algorithm, without impairing lightness of a data processing load on the reconstruction algorithm.
