Abstract
A method of performing x-ray spectroscopy surface material analysis of a region of interest of a sample with an evaluation system that includes a scanning electron microscope (SEM) column, an x-ray detector and an x-ray polarizer, comprising: positioning a sample within a field of view of the scanning electron microscope; generating an electron beam having a landing energy about equal to an ionization energy of the materials within the region of interest of the sample; scanning the region of interest with the electron beam set to collide with the sample thereby generating x-rays emitted from near a surface of the sample, the x-rays including characteristic x-rays and Bremsstrahlung radiation; and detecting x-rays generated while the region of interest is scanned by the electron after the x-rays pass through the x-ray polarizer that blocks a higher percentage of the Bremsstrahlung radiation than the characteristic x-rays.
