  • Patent number: 10283317
    Abstract: A method for TEM sample preparation and analysis that can be used in a FIB-SEM system without re-welds, unloads, user handling of the lamella, or a motorized flip stage. The method allows a dual beam FIB-SEM system with a typical tilt stage to be used to extract a sample to from a substrate, mount the sample onto a TEM sample holder capable of tilting, thin the sample using FIB milling, and rotate the sample so that the sample face is perpendicular to an electron column for STEM imaging.
    Type: Grant
    Filed: May 15, 2017
    Date of Patent: May 7, 2019
    Assignee: FEI Company

  • Publication number: 20060205206
    Abstract: A method is provided for processing a substrate including treating a surface of a dielectric layer comprising silicon and carbon by exposing the dielectric layer comprising silicon and carbon to a plasma of an inert gas, and depositing a photoresist on the dielectric layer comprising silicon and carbon. The dielectric layer may comprise a first dielectric layer comprising silicon, carbon, and nitrogen, and a second layer of nitrogen-free silicon and carbon containing material in situ on the first dielectric layer, and a third dielectric layer comprising silicon, oxygen, and carbon on the second dielectric layer.
