Extract

The focused ion beam miller (FIB) has been widely used in the semiconductor industry for many years, but only recently has its potential as a tool for materials science been recognised. The FIB uses a highly energetic beam of gallium ions to sputter material such that it can precisely section, as well as image, areas of interest. The FIB can be used to create crosssections, which can be examined in the FIB or in a scanning electron microscope (SEM). Cross sections can be made from delicate samples or samples in which a specific area needs to be viewed, for example to check the thickness of coatings or for failure analysis.

The FIB may also be used to prepare transmission electron microscope (TEM) specimens [1]. Extremely site-specific thin areas may be prepared with high positional accuracy from heterogeneous samples such as composites or layered structures.
