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).
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 ...
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 ...
One of these companies is TESCAN which was founded in 1991 by former Tesla development and service employees. The name TESCAN was derived from the words TESla and SCANning (scanning – screening). [3] TESCAN originally manufactured programmable controllers, digitizers for older analog scanning electron microscopes, and other small accessories.
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 ...
FEI Company (Field Electron and Ion Company) was an American company that designed, manufactured, and supported microscope technology.Headquartered in Hillsboro, Oregon, FEI had over 2,800 employees and sales and service operations in more than 50 countries around the world.
Scanning probe lithography. A scanning probe can be used for low-energy electron beam lithography, offering sub-100 nm resolution, determined by the dose of low-energy electrons. Another alternative in electron-beam lithography is to use extremely high electron energies (at least 100 keV) to essentially "drill" or sputter the material.
A scanning helium ion microscope (SHIM, HeIM or HIM) is an imaging technology based on a scanning helium ion beam. [2] Similar to other focused ion beam techniques, it allows to combine milling and cutting of samples with their observation at sub-nanometer resolution.
