    Abstract: A method for X-ray analysis of a sample includes directing a beam of X-rays to impinge on an area of a periodic feature on a surface of the sample and receiving the X-rays scattered from the surface in a reflection mode so as to detect a spectrum of diffraction in the scattered X-rays as a function of azimuth. The spectrum of diffraction is analyzed in order to determine a dimension of the feature.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: A method for inspection includes directing a beam of X-rays to impinge upon an area of a sample containing first and second features formed respectively in first and second thin film layers, which are overlaid on a surface of the sample. A pattern of the X-rays diffracted from the first and second features is detected and analyzed in order to assess an alignment of the first and second features.
