Serial sectioning using a combined FIB and SEM is a method for three-dimensional imaging of material microstructures. Hitachi set out to achieve precise three-dimensional imaging of material microstructures with higher spatial resolution and contrast than previous instruments by utilizing a configuration in which the FIB and SEM are positioned orthogonally (perpendicularly), this being the ideal orientation for three-dimensional imaging. This manuscript gives an overview of an FIB-SEM with an orthogonal configuration intended for three-dimensional imaging, describes the multi-functionality and high-performance imaging that are features of the instrument, presents examples of its use, and considers future developments.
