  • System and method of aligning a sample
    Publication number: 20090207408
    Abstract: A system and method of use thereof that enables determining and setting sample alignment based on the location of, and geometric attributes of a monitored image formed by reflection of an electromagnetic beam from a sample and into an image monitor, which beam is directed to be incident onto the sample along a locus which is substantially normal to the surface of the sample.
    Type: Application

    Publication date: August 20, 2009
    Inventors: Martin H. Liphardt, Blaine Johs
  • Deviation angle self compensating substantially achromatic retarder
    Publication number: 20070253059
    Abstract: A substantially achromatic multiple element compensator system for use in wide spectral range (for example, 190-1700 nm) rotating compensator spectroscopic ellipsometer and/or polarimeter systems. Multiple total internal reflections enter retardance into an entered beam of electromagnetic radiation, and the elements are oriented to minimize changes in the net retardance vs. the input beam angle resulting from changes in the position and/or rotation of the system of elements.

  • System for and method of investigating the exact same point on a sample substrate with multiple wavelengths
    Publication number: 20070097373
    Abstract: Disclosed are system for and method of analyzing a sample at substantially the exact same small spot point on a sample with a plurality of wavelengths.
