  • Patent number: 9658174
    Abstract: Disclosed is an X-ray topography apparatus including an X-ray source, a multilayer film mirror, a slit, a two-dimensional X-ray detector, and a sample moving device that sequentially moves the sample to a plurality of step positions. The X-ray source is a minute focal spot. The multilayer film mirror forms monochromatic, collimated, high-intensity X-rays. The direction in which the multilayer film mirror collimates the X-rays coincides with the width direction of the slit. The step size by which the sample is moved is smaller than the width of the slit. The combination of the size of the minute focal spot, the width of the slit, and the intensity of the X-rays that exit out of the multilayer film mirror allows the contrast of an X-ray image produced when the detector receives X-rays for a predetermined period of 1 minute or shorter to be high enough for observation of the X-ray image.
    Type: Grant

  • Patent number: 7258485
    Abstract: An X-ray thin film inspection apparatus including a sample table on which an inspection target such as a product wafer or the like is mounted, a positioning mechanism for moving the sample table, a goniometer having first and second swing arms, at least one X-ray irradiation unit that are mounted on the first swing arm and containing an X-ray tube and an X-ray optical element in a shield tube, an X-ray detector mounted on a second swing arm, and an optical camera for subjecting the inspection target disposed on the sample table to pattern recognition.
