  • Charged-particle source, control system and process using gating to extract the charged particle beam
    Patent number: 6225747
    Abstract: A control system and process for operating a charged-particle source which achieves gating of the charged-particle beam without a mechanical shutter and with very short transition between the beam “on” and beam “off” states is presented. The process and control system provide very precise control of the duration of the charged-particle extraction.
    Type: Grant
    Filed: August 9, 1999
    Date of Patent: May 1, 2001
    Assignee: Veeco Instruments Inc.
    Inventors: Roger P. Fremgen, Jr., John Jacob, Alan V. Hayes, Victor Kanarov, Edward W. Ostan, Abraham J. Navy, Emmanuel N. Lakios, Genrikh Treyger
