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).
Electron-beam-induced deposition (EBID) is a process of decomposing gaseous molecules by an electron beam leading to deposition of non-volatile fragments onto a nearby substrate. The electron beam is usually provided by a scanning electron microscope , which results in high spatial accuracy (potentially below one nanometer) and the possibility ...
Operating principle of a transmission electron microscope. Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid.
An electron beam is produced by an electron gun, with the electrons typically having energies in the range 20 to 400 keV, focused by electromagnetic lenses, and transmitted through the specimen. When it emerges from the specimen, the electron beam carries information about the structure of the specimen that is magnified by lenses of the microscope.
EBIC – Electron beam induced current (see IBIC: ion beam induced charge) EBS – Elastic (non-Rutherford) backscattering spectrometry (see RBS) EBSD – Electron backscatter diffraction; ECOSY – Exclusive correlation spectroscopy; ECT – Electrical capacitance tomography; EDAX – Energy-dispersive analysis of x-rays
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.
An electrostatic lens is a device that assists in the transport of charged particles. [1] [2] [3] For instance, it can guide electrons emitted from a sample to an electron analyzer, analogous to the way an optical lens assists in the transport of light in an optical instrument.
Ion-beam lithography is the practice of scanning a focused beam of ions in a patterned fashion across a surface in order to create very small structures such as integrated circuits or other nanostructures.
