    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.
