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).
Image of pollen grains taken on a SEM shows the characteristic depth of field of SEM micrographs M. von Ardenne's first SEM SEM with opened sample chamber Analog type SEM. A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons.
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 ...
Some LVEMs can function as an SEM, a TEM, and a STEM in a single compact instrument. Using a low beam voltage increases image contrast which is especially important for biological specimens. This increase in contrast significantly reduces, or even eliminates the need to stain biological samples.
TESCAN is one of the world's leading manufacturers of Scanning Electron Microscopes (SEM), Focused Ion Beam-Scanning Electron Microscopes (FIB-SEM), Scanning Transmission Electron Microscopes (STEM), and microcomputed tomography (microCT). TESCAN serves customers in materials science, geosciences, life sciences and semiconductor markets.
The good news is that the farrier is in the area and can shoe your horse right away. However, in all the excitement your horse is having far too much fun to be caught.
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.
