आयन-बीम इसके अंग्रेजी अर्थ का उदाहरण

FIB can also be incorporated in a system with both electron and ion beam columns, allowing the same feature to be investigated using either of the beams.

LMIS produce high current density ion beams with very small energy spread.

Focused ion beam (FIB) systems have been produced commercially for approximately twenty years, primarily for large semiconductor manufacturers.

As the diagram on the right shows, the gallium (Ga+) primary ion beam hits the sample surface and sputters a small amount of material, which leaves the surface as either secondary ions (i+ or i−) or neutral atoms (n0).

In this manner, by imaging with positive secondary ions using the positive primary ion beam, even highly insulating samples may be imaged and milled without a conducting surface coating, as would be required in an SEM.

At lower beam currents, FIB imaging resolution begins to rival the more familiar scanning electron microscope (SEM) in terms of imaging topography, however the FIB's two imaging modes, using secondary electrons and secondary ions, both produced by the primary ion beam, offer many advantages over SEM.

Another advantage of FIB secondary electron imaging is the fact that the ion beam does not alter the signal from fluorescent probes used in the labelling of proteins, thus creating the opportunity to correlate FIB secondary electron images with images obtained by fluorescence microscopes.

A FIB can also be used to deposit material via ion beam induced deposition.

This damaged layer can be minimized by FIB milling with lower beam voltages, or by further milling with a low-voltage argon ion beam after completion of the FIB process.

The ejected secondary ions are collected and analyzed after the surface of the specimen has been sputtered with a primary focused ion beam.

The focused ion beam has become a powerful tool for site-specific 3D imaging of sub-micron features in a sample.

In this FIB tomography technique, the sample is sequentially milled using an ion beam perpendicular to the specimen while imaging the newly exposed surface using an electron beam.
