    Abstract: A method for analysis includes directing a converging beam of X-rays toward a surface of a sample having multiple single-crystal layers, including at least a first layer and a second layer that is formed over and tilted relative to the first layer. The X-rays that are diffracted from each of the first and second layers are sensed simultaneously while resolving the sensed X-rays as a function of angle so as to generate a diffraction spectrum including at least a first diffraction peak due to the first layer and a second diffraction peak due to the second layer. The diffraction spectrum is analyzed so as to identify a characteristic of at least the second layer.

    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 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.

    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 inspection of a sample includes directing a beam of X-rays toward a sample and configuring an array of detector elements to capture the X-rays scattered from the sample. The sample is shifted in a direction parallel to the axis of the array between at least first and second positions, which positions are separated one from another by an increment that is not an integer multiple of the pitch of the array. At least first and second signals are generated by the detector elements responsively to the X-rays captured thereby while the sample is in at least the first and second positions, respectively. The first and second signals are combined so as to determine an X-ray scattering profile of the sample as a function of position along the axis.

    Abstract: Apparatus for X-ray excitation of a sample, including a substantially stationary X-ray source and X-ray optics, including at least one secondary target and a movable element. The movable element has at least a first position wherein X-rays emitted by the source excite the sample directly, and a second position wherein X-rays emitted by the source strike the at least one secondary target, causing the secondary target to emit X-rays that excite the sample, while the X-rays emitted by the source are substantially prevented from exciting the sample.
