  • HYBRID ELECTROSTATIC LENS WITH INCREASED NATURAL FREQUENCY
    Publication number: 20150048254
    Abstract: A composite electrostatic rod may include a body comprising a length L and cross sectional area A. The body may include an outer portion comprising a first material, and a core comprising a second material different than the first material and surrounded by the outer portion, wherein a natural frequency of the composite electrostatic rod is greater than that of a graphite rod having the length L and cross sectional area A.
    Type: Application

  • Mask position detection
    Publication number: 20080073569
    Abstract: A system includes a transfer arm defining a retaining plane, and at least three sensors are disposed on the transfer arm and configured to detect a position of a mask relative to the retaining plane. The at least three sensors may be used to determine if the mask is properly positioned on the transfer arm and to determine if the mask is properly positioned in a masking position. The mask may be used in an ion implanter to shield portions of a workpiece from ion implantation.
