Abstract:
A system and method for failure analysis of devices on a semiconductor wafer is disclosed. The present invention comprises the use of an inline focused ion beam milling tool to perform milling and image capturing of cross sections of a desired inspection point. The inspection points are located by identifying at least one fiducial that corresponds to an X-Y offset from the desired inspection point. The fiducials are recognized by a computer vision system. By automating the inspection process, the time required to perform the inspections is greatly reduced.
