A FIB workstation. Focused ion beam, also known as FIB, is a technique used particularly in the semiconductor industry, materials science and increasingly in the biological field for site-specific analysis, deposition, and ablation of materials. A FIB setup is a scientific instrument that resembles a scanning electron microscope (SEM).
Electron channelling contrast imaging (ECCI) is a scanning electron microscope (SEM) diffraction technique used in the study of defects in materials. These can be dislocations or stacking faults that are close to the surface of the sample, low angle grain boundaries or atomic steps.
In 2013, TESCAN ORSAY HOLDING was established following the merger of the Czech company TESCAN, a leading global developer and supplier of scanning electron microscopes (SEMs) and focused ion beam (FIB) workstations, and the French company ORSAY PHYSICS, a world leader in customized Focused Ion Beam and Electron Beam technology.

A serial block-face scanning electron microscope consists of an ultramicrotome mounted inside the vacuum chamber of a scanning electron microscope. Samples are prepared by methods similar to that in transmission electron microscopy ( TEM ), typically by fixing the sample with aldehyde, staining with heavy metals such as osmium and uranium then ...
A single excavation site exposes a cross section for analysis using a scanning electron microscope. Dual excavations on either side of a thin lamella bridge are utilized for preparing transmission electron microscope samples. [2] Another common use of FIB instruments is for design verification and/or failure analysis of semiconductor devices ...
Only SEM-like imaging using secondary electrons is possible, and even that imaging is restricted to short observations due to sample damaging by the Ga + beam. The use of a dual beam instrument, that combines a FIB and an SEM in one, circumvents this limitation. The advantages of IBID are: Much higher deposition rate; Higher purity

Scanning electron microscope image of a thin TEM sample milled by FIB. The thin membrane shown here is suitable for TEM examination; however, at ~300-nm thickness, it would not be suitable for high-resolution TEM without further milling. More recently focused ion beam methods have been used to prepare samples. FIB is a relatively new technique ...
