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).
The E-T secondary electron detector can be used in the SEM's back-scattered electron mode by either turning off the Faraday cage or by applying a negative voltage to the Faraday cage. However, better back-scattered electron images come from dedicated BSE detectors rather than from using the E–T detector as a BSE detector.
A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM). Pronunciation is [stɛm] or [ɛsti:i:ɛm]. As with a conventional transmission electron microscope (CTEM), images are formed by electrons passing through a sufficiently thin specimen. However, unlike CTEM, in STEM the electron beam is focused ...
Carl Zeiss Crossbeam 550 – combines a field emission scanning electron microscope (FE-SEM) with a focused ion beam (FIB). Nanofluidics channels fabricated with a Zeiss Crossbeam 550 L, in a silicon master stamp. Ion beams can be used for material modification (e.g. by sputtering or ion beam etching) and for ion beam analysis.
Deposition occurs in a focused ion beam (FIB) setup, which strongly limits characterization of the deposit during or right after the deposition. 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 ...
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.

An electron microscope uses a controlled beam of electrons to illuminate a specimen and produce a magnified image. Two common types are the scanning electron microscope (SEM) and the transmission electron microscope (TEM).
Serial block-face scanning electron microscopy is a method to generate high resolution three-dimensional images from small samples. The technique was developed for brain tissue, but it is widely applicable for any biological samples. [ 1 ]
