  • Patent number: 6664541
    Abstract: The present invention includes a system for localization of defects in test samples. A sample is scanned using a particle beam. Some particles interact with conductive elements and may cause the emission of x-rays. Other particles can pass through the sample entirely and generate a current that can be measured. A higher current generated indicates less conductive material at the scan target that may mean a void, dishing, or erosion is present. Localization of a defect can be confirmed using an x-ray emission detector.
    Type: Grant
    Filed: November 21, 2001
    Date of Patent: December 16, 2003
    Assignee: KLA Tencor Technologies Corporation
