  • Patent number: 7173648
    Abstract: The present invention relates to visually monitoring an interior portion of a processing chamber in a semiconductor processing system. An image collector collects images of the interior of the chamber and provides an image signal indicative of a visual representation of the interior of the chamber. A viewing station receives the image signal and displays a visual representation of the interior of the chamber.

  • Patent number: 7080330
    Abstract: A system and methodology are disclosed for monitoring and controlling a semiconductor fabrication process. One or more structures formed on a wafer matriculating through the process facilitate concurrent measurement of critical dimensions and overlay via scatterometry or a scanning electron microscope (SEM). The concurrent measurements mitigate fabrication inefficiencies, thereby reducing time and real estate required for the fabrication process. The measurements can be utilized to generate feedback and/or feed-forward data to selectively control one or more fabrication components and/or operating parameters associated therewith to achieve desired critical dimensions and to mitigate overlay error.
