X-ray imaging system and image processing method
The X-ray imaging system of this invention includes: a detecting member which detects a salt and pepper noise region in the reconstructed image based on at least one characteristic value of the moire stripe image not including the object and/or the moire stripe image including the object; a masked-image generating member which generates a masked image for identifying the detected salt and pepper noise region; and an image processing member which masks or trims at least one of the reconstructed image and the moire stripe images with the generated masked image.
A Method And System For Analyzing An Object By Diffractometry Using A Scattering Spectrum And A Transmission Spectrum
A method for analyzing an object includes irradiating the object with incident photon radiation and acquiring an energy spectrum scattered by the material using a spectrometric detector in scatter mode. An energy spectrum transmitted by the material is acquired using a spectrometric detector in transmission mode. A signature (f) is reconstructed representing the object, both from the scatter spectrum measured and from the transmission spectrum measured, and the reconstructed signature thereof is compared with signatures of standard materials.
X-ray topography apparatus
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.
A Method Of Analyzing An Object In Two Stages Using A Transmission Spectrum Then A Scattering Spectrum
A method for analyzing an object, includes irradiating the object with incident photon radiation, acquiring a spectrum transmitted by the object using a spectrometric transmission detector, determining at least one first property of the object from the transmission spectrum, verifying that at least one doubt criterion relating to the first property of the object is met, and translating the fact that the object contains a material that is potentially dubious for the application under consideration. A second part, carried out only when the doubt criterion is met, includes acquiring an energy spectrum scattered by the object using a spectrometric scattering detector at an angle of 1 to 15, and determining a second property of the object from at least the scatter spectrum and comparing at least the second property of the object with properties of standard materials stored in a database to identify the objects composition material.
Parameterizing x-ray scattering measurement using slice-and-image tomographic imaging of semiconductor structures
Semiconductor structures can be investigated, e.g., in an in-line quality check. An x-ray scattering measurement, e.g., CD-SAXS, can be used for wafer metrology. The x-ray scattering measurement can be configured based on a slice-and-imaging tomographic measurement using a dual-beam device, e.g., including a focused ion beam device and a scanning electron microscope.
