    Abstract: A method of performing x-ray spectroscopy material analysis of a region of interest within a cross-section of a sample using an evaluation system that includes a focused ion beam (FIB) column, a scanning electron microscope (SEM) column, and an x-ray detector, including: forming a lamella having first and second opposing side surfaces in the sample by milling, with the FIB column, first and second trenches in the sample to expose the first and second sides surface of the lamella, respectively; depositing background material in the second trench, wherein the background material is selected such that the background material does not include any chemical elements that are expected to be within the region of interest of the sample; generating a charged particle beam with the SEM column and scanning the charged particle beam across a region of interest on the first side surface of the lamella such that the charged particle beam collides with the first side surface of the lamella at a non-vertical angle; and detecting x-rays generated while the region of interest is scanned by the charged particle beam.

    Abstract: A method of evaluating a region of a sample that includes an array of holes separated by solid portions. The method includes positioning the sample within in a vacuum chamber of an evaluation tool that includes a scanning electron microscope (SEM) column and a focused ion beam (FIB); injecting a deposition gas onto the sample; scanning, with a first charged particle beam, a portion of the sample that includes a plurality of holes in the array of holes to locally deposit material within the plurality of holes in the scanned portion from the deposition gas; and milling, with the FIB column, the portion of the sample that includes the plurality of holes in which the material was locally deposited.

    Abstract: A method that includes performing multiple test iterations to provide multiple test results; and processing the multiple test results to provide estimates of a conductivity of each of the multiple bottoms segments. The multiple test iterations includes repeating, for each bottom segment of the multiple bottom segments, the steps of: (a) illuminating the bottom segment by a charging electron beam; wherein electrons emitted from the bottom segment due to the illuminating are prevented from exiting the hole; (b) irradiating, by a probing electron beam, an area of an upper surface of the dielectric medium; (c) collecting electrons emitted from the area of the upper surface as a result of the irradiation of the area by the probing electron beam to provide collected electrons; and (d) determining an energy of at least one of the collected electrons to provide a test result.
