CAD Navigation System NASFA (Navigation System for Failure Analysis)

The CAD Navigation System for Failure Analysis (NASFA) is used to identify the location on the CAD data corresponding to the LSI pattern being observed with a SEM or FIB system. When the coordinates on the CAD data are specified, the sample stage moves to the particular coordinates, displaying the corresponding SEM image (or SIM image for the FIB). The CAD data and SEM image can be overlaid and it is easy to verify the lower-layer line location, significantly improving the efficiency of analysis and repair work.
