At the point of contact with the target the beam is less than 5 Nanometers in size. By controlling the power of the Ion stream the beam can be used to either cut or add traces to the circuit.
FIB is a very powerful tool for the reverse engineer allowing them to actually change the characteristics of the design. In addition, the Micrion 9500 includes a Scanning Electron Microscope producing crystal clear images of semiconductors and optical disc surfaces at 300,000 X magnification.
