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).
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
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.
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.
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.
Just weeks later on Oct. 27, the day before her 19th birthday, she underwent surgery to remove the mass. Six weeks of radiation therapy followed, with Strahan documenting each step of the way .
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 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 ...
