  • Publication number: 20110168554
    Abstract: An apparatus for treatment of a sample for the manufacture of integrated circuits includes a holder apparatus and a stage which is coupled to the holder apparatus. The stage is capable of holding a portion of a sample to be analyzed. The apparatus also includes a shield that is operably coupled to the stage to block a portion of the sample. The shield is capable of movement relative to the sample to block one or more portions of the sample. The shield is provided on a track member and is movable from a first spatial location to a second spatial location on the track member. The apparatus further includes an enclosure surrounding an entirety of the sample and the shield.

  • Patent number: 7927893
    Abstract: A method for analyzing a sample for the manufacture of integrated circuits, e.g. MOS transistors, application specific integrated circuits, memory devices, microprocessors, system on a chip. The method includes providing an integrated circuit chip, which has a surface area with at least one region of interest, e.g., bond pad. The method includes covering a first portion of the surface area including the region of interest using a blocking material. The method also forms a metal layer on a second portion of the surface area, while the blocking material protects the first portion. The method removes the blocking material to expose the first portion of the surface area including the region of interest. The method also subjects the metal layer to a voltage differential to draw away one or more charged particles from the first portion of the surface area. The method also subjects the surface area including the region of interest to spectrometer analysis.
