Focused Ion Beam (FIB) System

Focused Ion Beam Writing

As the diagram on the right shows,the gallium (Ga+) primary ion beam hitsthe sample surface and sputters a smallamount of material, which leaves thesurface as either secondary ions (i+ or i-) or neutral atoms (n0). The primary beam also produces secondary electrons (e-).As the primary beam rasters on the samplesurface, the signal from the sputtered ionsor secondary electrons is collected to forman image.
