  • Publication number: 20210257181
    Abstract: Apparatuses, systems, and methods for transferring fluid to a stage in a charged particle beam system are disclosed. In some embodiments, a stage may be configured to secure a wafer; a chamber may be configured to house the stage; and a tube may be provided within the chamber to transfer fluid between the stage and outside of the chamber. The tube may include a first tubular layer of first material, wherein the first material is a flexible polymer; and a second tubular layer of second material, wherein the second material is configured to reduce permeation of fluid or gas through the tube. In some embodiments, a system may include a degasser system outside of the chamber, where the degasser system may be configured to remove gases from the transfer fluid before the transfer fluid enters the tube.

  • Patent number: 6614532
    Abstract: The present invention comprises an apparatus and a method of microscopy, for measuring depth dependent profiles of optical absorption, photoluminescence and light scattering in thin films on length scales of a few micrometers to a several millimeters. The principles of this invention are also directly extendable to imaging absorption and scattering at other wavelengths, and the scattering of electrons, and neutrons in thin films on the same or shorter length scales. In the optical range, this depth profile information is recovered by the direct recording of micrometer scale images of a light beam propagating along the depth axis of the material under study. The recording is implemented using a crossed beam microscope apparatus in which a collimated optical beam from a light source is propagated through the material under test.
