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).
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. [3] In terms of imaging, SHIM has several advantages over the traditional ...
It is known that focused-ion beam lithography has the capability of writing extremely fine lines (less than 50 nm line and space has been achieved) without proximity effect. [17] However, because the writing field in ion-beam lithography is quite small, large area patterns must be created by stitching together the small fields.

Cells must be identified and targeted with a high degree of accuracy. This can be accomplished using cell staining and fluorescence microscopy or without staining through the use of techniques such as quantitative phase microscopy or phase contrast microscopy. Ultimately, the objective is to recognize cells, target them, and move them into ...
Ion-beam lithography offers higher resolution patterning than UV, X-ray, or electron beam lithography because these heavier particles have more momentum. This gives the ion beam a smaller wavelength than even an e-beam and therefore almost no diffraction. The momentum also reduces scattering in the target and in any residual gas.
Few periods of life are more closely monitored and supervised than during one's pregnancy. Throughout this time, trained medical professionals conduct a series of prenatal visits with the mother ...
The sample is placed in the vacuum chamber of the electron microscope. Both analysis methods are then performed automatically at the same sample location. The obtained SEM and Raman images can then be superimposed. [20] [21] Moreover, adding a focused ion beam (FIB) on the chamber allows removal of the material and therefore 3D imaging of the ...
