    摘要: Apparatus for analysis of a sample includes a radiation source, which is adapted to direct a converging beam of X-rays toward a surface of the sample. At least one detector array is arranged to sense the X-rays scattered from the sample as a function of elevation angle over a range of elevation angles simultaneously, and to generate output signals responsively to the scattered X-rays. The detector array has a first configuration in which the detector array senses the X-rays that are reflected from the surface of the sample at a grazing angle, and a second configuration in which the detector array senses the X-rays that are diffracted from the surface in a vicinity of a Bragg angle of the sample. A signal processor processes the output signals so as to determine a characteristic of the surface layer of the sample.

    摘要: Reflectometry apparatus includes a radiation source, adapted to irradiate a sample with radiation over a range of angles relative to a surface of the sample, and a detector assembly, positioned to receive the radiation reflected from the sample over the range of angles and to generate a signal responsive thereto. A shutter is adjustably positionable to intercept the radiation, the shutter having a blocking position, in which it blocks the radiation in a lower portion of the range of angles, thereby allowing the reflected radiation to reach the array substantially only in a higher portion of the range, and a clear position, in which the radiation in the lower portion of the range reaches the array substantially without blockage.

    摘要: A method for X-ray analysis of a sample includes aligning an optical radiation source with an X-ray excitation source, so that a spot on the sample that is irradiated by an X-ray beam generated by the X-ray excitation source is illuminated with optical radiation generated by the optical radiation source. Optical radiation that is reflected from the sample is used to generate a first signal, which is indicative of an alignment of the spot on the sample. The X-ray beam is aligned, responsively to the first signal, so that the spot coincides with a target area of the sample. X-ray photons received from the spot on the sample, after aligning the X-ray beam, are used in generating a second signal that is indicative of a characteristic of the target area.

    摘要: Apparatus for X-ray microanalysis of a sample includes an X-ray source, which irradiates a spot having a dimension less than 500 &mgr;m on a surface of the sample. A first X-ray detector captures fluorescent X-rays emitted from the sample, responsive to the irradiation, at a high angle relative to the surface of the sample. A second X-ray detector captures X-rays from the spot at a grazing angle relative to the surface of the sample. Processing circuitry receives respective signals from the first and second X-ray detectors responsive to the X-rays captured thereby, and analyzes the signals in combination to determine a property of a surface layer of the sample within the area of the spot.

    摘要: A method for testing the deposition and/or the removal of a material within a recess on the surface of a sample. An excitation beam is directed onto a region of the sample in a vicinity of the recess, and an intensity of X-ray fluorescence, emitted from the region in a spectral range in which the material is known to fluoresce, is measured. A quantity of the material that is deposited within the recess is determined responsive to the measured intensity.

    摘要: A method for inspection of a sample includes directing an excitation beam to impinge on an area of a planar sample that includes a feature having sidewalls perpendicular to a plane of the sample, the sidewalls having a thin film thereon. An intensity of X-ray fluorescence (XRF) emitted from the sample responsively to the excitation beam is measured, and a thickness of the thin film on the sidewalls is assessed based on the intensity. In another method, the width of recesses in a surface layer of a sample and the thickness of a material deposited in the recesses after polishing are assessed using XRF.
