  • Substrate measurement apparatus with electron distortion unit
    Patent number: 9009861
    Abstract: Provided is a fusion measurement apparatus which increases or maximizes the reliability of a measurement. The fusion measurement apparatus includes an atomic microscope for measuring a surface of a substrate at an atomic level, an electron microscope for measuring the atomic microscope and the substrate, and at least one electrode which distorts the path of a secondary electron on the substrate covered by a cantilever of the atomic microscope so that the secondary electron proceeds to an electron detector of the electron microscope.
    Type: Grant
    Filed: June 24, 2011
    Date of Patent: April 14, 2015
    Assignee: Korea Research Institute of Standards and Science
    Inventors: Byong Chon Park, Ju Youb Lee, Woon Song, Jin Ho Choi, Sang Jung Ahn, Joon Lyou, Won Young Song, Jae Wan Hong, Seung Hun Baek
