Abstract: An x-ray apparatus, that may include a mount that is configured to hold a sample; an x-ray source, that is configured to direct an x-ray beam toward a first side of the sample; a detector, positioned downstream to a second side of the sample, the detector is configured to detect, during a sample measurement period, at least a part of x-rays that have been transmitted through the sample; and an x-ray intensity detector that is positioned, during a beam intensity monitoring period at a measurement position that is located between the x-ray source and the first side of the sample, so as to detect at least a part of the x-ray beam before the x-ray beam reaches the sample.

Abstract: A system includes first and second imaging assemblies, and a processor. The first imaging assembly is configured to produce a first image of a measurement site in a sample. The second imaging assembly is coupled with a measurement assembly and is configured to produce a second image of the measurement site. The processor is configured to: (i) perform, based on the first image, a first movement of the sample relative to the measurement assembly, (ii) perform, based on the second image, a second movement of the sample for aligning the sample with the measurement assembly, and (iii) control the measurement assembly to perform a measurement in the measurement site.

Abstract: A method for evaluating an array of high aspect ratio (HAR) structures on a sample includes illuminating the sample with an x-ray beam along a first axis parallel to within two degrees to the HAR structures in the array and sensing a first pattern of small angle x-ray scattering (SAXS) scattered from the sample while illuminating the sample along the first axis. The sample is illuminated with the x-ray beam along a second axis that is oblique to the HAR structures in the array, and a second pattern of the SAXS scattered from the sample is sensed while illuminating the sample along the second axis. Information is extracted with respect to the HAR structures based on the first and second patterns.
