    Abstract: A method of characterizing a device under test (DUT) includes illuminating the DUT with a broadband optical beam within an optical field of view (FOV), illuminating the DUT with an X-ray beam within an X-ray FOV overlapping the optical FOV, and concurrently acquiring X-ray metrology information, e.g., one or more X-ray images utilizing various modalities, such as absorption, phase contrast difference, darkfield, small angle X-ray scattering (SAXS) and/or fluorescence, from the X-ray FOV and a plurality of optical images of the optical FOV, each of the optical images corresponding to respective selected wavelengths of the broadband optical beam from each of ultraviolet, visible, and infrared wavelengths, for example including deep ultraviolet, near infrared, or short-wavelength infrared wavelengths. The DUT may be one or more substrates, e.g., stacked, and include electronic devices such as three-dimensional integrated devices.

    Abstract: Provided is an evaluation method that can easily evaluate the percentage of voids in a rubber material. The present disclosure relates to an evaluation method including evaluating the percentage of voids in a rubber material with a strain applied thereto based on the φvoid calculated from the following Equation (1) using the transmittance and thickness of the rubber material with no strain applied thereto and the transmittance and thickness of the rubber material with the strain applied thereto.

    Abstract: An X-ray system includes, first and second X-ray channels (XCs), a spot sizer and a processor. The first XC is configured to: (i) direct a first X-ray beam for producing a spot on a surface of a sample, and (ii) produce a first signal responsively to a first X-ray radiation received from the surface. The spot sizer is positioned at a distance from the surface and is shaped and positioned to set the spot size by passing to the surface a portion of the first X-ray beam. The second XC is configured to: (i) direct a second X-ray beam to the surface, and (ii) produce a second signal responsively to a second X-ray radiation received from the surface, and the processor is configured to: (i) perform an analysis of the sample based on the first signal, and (ii) estimate the size of the spot based on the second signal.
