Patent number: 7649978Abstract: The computer-implemented method for inspection of a sample includes defining a plurality of locations on a surface of the sample, irradiating the surface at each of the locations with a beam of X-rays, and measuring an angular distribution of the X-rays that are emitted from the surface responsively to the beam, so as to produce a respective plurality of X-ray spectra. The X-ray spectra are analyzed to produce respective figures-of-merit indicative of a measurement quality of the X-ray spectra at the respective location. One or more locations are selected out of the plurality of locations responsively to the figures-of-merit, and a property of the sample is estimated using the X-ray spectra measured at the selected location.Type: GrantFiled: September 12, 2008Date of Patent: January 19, 2010Assignee: Jordan Valley Semiconductors Ltd.Inventors: Isaac Mazor, Alex Dikopoltsev, Boris Yokhin, Dileep Agnihotri, Tzachi Rafaeli, Alex Tokar, David Berman, Moshe Beylin

Patent number: 7551719Abstract: Apparatus for analysis of a sample includes a radiation source, which is adapted to direct a first, converging beam of X-rays toward a surface of the sample and to direct a second, collimated beam of the X-rays toward the surface of the sample. A motion assembly moves the radiation source between a first source position, in which the X-rays are directed toward the surface of the sample at a grazing angle, and a second source position, in which the X-rays are directed toward the surface in a vicinity of a Bragg angle of the sample. A detector assembly senses the X-rays scattered from the sample as a function of angle while the radiation source is in either of the first and second source configurations and in either of the first and second source positions. A signal processor receives and processes output signals from the detector assembly so as to determine a characteristic of the sample.Type: GrantFiled: August 10, 2005Date of Patent: June 23, 2009Assignee: Jordan Valley Semiconductord LtdInventors: Boris Yokhin, Alexander Krokhmal, Tzachi Rafaeli, Isaac Mazor, Amos Gvirtzman

Patent number: 7245695Abstract: A method for testing a material applied to a surface of a sample includes directing an excitation beam, having a known beam-width and intensity cross-section, onto a region of the sample. An intensity of X-ray fluorescence emitted from the region responsively to the excitation beam is measured. A distribution of the material within the region is estimated, responsively to the measured intensity of the X-ray fluorescence and to the intensity cross-section of the excitation beam, with a spatial resolution that is finer than the beam-width.Type: GrantFiled: April 11, 2005Date of Patent: July 17, 2007Assignee: Jordan Valley Applied Radiation Ltd.Inventors: Isaac Mazor, Alex Dikopoltsev, Boris Yokhin, Tzachi Rafaeli, Alex Tokar
