Abstract
A method for X-ray measurement includes, in a calibration phase, scanning a first X-ray beam, having a first beam profile, across a feature of interest on a calibration sample and measuring first X-ray fluorescence (XRF) emitted from the feature and from background areas of the calibration sample surrounding the feature. Responsively to the first XRF and the first beam profile, a relative emission factor is computed. In a test phase, a second X-ray beam, having a second beam profile, different from the first beam profile, is directed to impinge on the feature of interest on a test sample and second XRF emitted from the test sample is measured in response to the second X-ray beam. A property of the feature of interest on the test sample is computed by applying the relative emission factor together with the second beam profile to the measured second XRF.
