Web10 apr. 2024 · Helium bubble growth under different helium ion implantation. Transmission electron microscopy (Talos f200x G2 TEM) was used to observe the cross-section of the silicon wafer. The cross-section TEM slices were prepared by focused ion beam (FIB) stripping technology, and the slice thickness was approximately 50 nm. Web24 nov. 2008 · This provides the helium ion microscope with greater signal at a given beam current and greater material contrast. Figure 2 shows an example of this, comparing the SE image from a conventional SEM (Figure 2a) to a helium ion microscope (Figure 2b). Both images show surface topology, but the helium ion image displays two features …

It is an enabling technology that not only provides imagery of conducting as well as uncoated insulating nano–structures but also allows to create these features. WebThe helium ion microscope (HIM) is a new type of microscope that uses a focused beam of helium ions for surface imaging and analysis [213–217]. Helium ions are about 8000 times heavier than electrons with a de Broglie wavelength that is approximately 300 times smaller than an electron beam. lauren totty
