  • Publication number: 20250231132
    Abstract: Disclosed herein is a system for non-destructive characterization of specimens. The system includes an electron beam (e-beam) source for projecting e-beams at one or more e-beam landing energies on a specimen; an X-ray detector for sensing X-rays emitted from the specimen, thereby obtaining measurement data; and a processing circuitry. The processing circuitry is configured to: (i) extract from the measurement data key features specified by a vector {right arrow over (ƒ)}key; and (ii) estimate values {right arrow over (p)} of one or more structural parameters characterizing the specimen, based on {right arrow over (ƒ)}key and a set of vectors of key features {{right arrow over (ƒ)}n}n=1N of ground truth (GT) reference specimens. Each of the {right arrow over (ƒ)}n is a product of measurements of emission of X-rays from a reference specimen due to impinging thereof with e-beams at each of the one or more landing energies.

  • Publication number: 20240255449
    Abstract: Disclosed herein is a system for non-destructive classification of specimens. The system includes an e-beam source, an X-ray measurement module, and a computational module. The e-beam source is configured to project e-beams on a specimen at one or more e-beam landing energies, so as to penetrate the specimen and induce emission of X-rays. The X-ray measurement module is configured to measure the emitted X-rays. The computational module is configured to process the measurement data to obtain an energy signature of at least one target substance included in the specimen and classify the inspected specimen based on the obtained energy signature and one or more reference energy signatures pertaining to one or more reference specimens, respectively.

  • Publication number: 20240085356
    Abstract: A computer-based method for non-destructive z-profiling of samples. The method includes: a measurement operation and a data analysis operation. The measurement operation includes, for each of a plurality of landing energies: (i) projecting an electron beam on a sample at a respective landing energy, such that light-emitting interactions between electrons from the electron beam and the sample occur within a respective probed region of the sample, which is centered about a respective depth; and (ii) measuring the emitted light to obtain an optical emission data set of the sample. The data analysis operation includes obtaining from the measured optical emission data sets a concentration map quantifying a dependence of a concentration of a material, which the sample comprises, on at least the depth.

    Abstract: There is provided a system and method of examining a specimen comprising a first layer and a second layer. The method comprises obtaining a recipe including a template image for each reference polygon in a reference image and a template mask indicative of proximity of a set of locations in the template image to an edge of the reference polygon; obtaining an inspection image in runtime; identifying first inspection polygons in the inspection image corresponding to the first reference polygons using template images and template masks thereof; determining a first shift for the first layer based on the first locations, and registering the first reference polygons with the inspection image based on the first shift. Similarly, a second shift for the second layer can be determined, and the second reference polygons can be registered with the inspection image based on the second shift.

  • Patent number: 11037319
    Abstract: Systems and methods are described, including a system (100) for automatically ascertaining a height characteristic of a contaminant (104) on a travel surface (102). The system (100) comprises an illumination and imaging device (106). At a first time, when the travel surface (102) is generally free of contaminant, the illumination and imaging device (106) illuminates the travel surface (102) with at least one light beam (119), and images at least one impingement of the at least one light beam (119). At a second time, when the travel surface (102) is covered by a layer of contaminant (104), the illumination and imaging device (106) illuminates the travel surface with a light beam (132), and images an impingement of the light beam on an impingement surface (107). In response to the imaging, a computer (130) calculates the height characteristic of the contaminant. Other embodiments are also described.
