Specific solutions for specific needs

With the launch of XEIA3, TESCAN not only delivers an instrument top of its class but also fulfils its commitment to continue helping researchers to push science and development forward. This is also reflected in the careful customisation of every system in order to meet specific needs. From materials sciences to life sciences or from engineering to semiconductor industry, TESCAN is ready to take up the challenges of the upcoming future. 

Extend the capabilities in all your FIB applications with Xe plasma ion source

The XEIA3 combines the capabilities of an outstandingly fast and powerful xenon plasma ion source with an ultra-high resolution electron column. Such synergy allows for carrying out the most challenging large volume removal applications in beating times which have – up until now – never been achievable before. For research or for high-tech industry the highest precision that only a sub-2 nanometre electron column is guaranteed and opens new possibilities in a wider range of applications. The high current capable plasma ion source allows for a wider range of applications.



Semiconductors and Microelectronics

Xe plasma source provides great advantages for making the most of chemical and compositional analytical techniques such as energy and wavelength dispersive X-ray spectroscopy, 3D EDX and 3D EBSD reconstructions as well as full integration with TOF-SIMS for achieving superior resolution in surface analysis. XEIA3 is an extraordinary robust analytical platform with far reaching research potential in materials science.

  • ‚‚ Research in new materials and their characterisation
  • ‚‚ Study of non-conductive materials such as crystals, ceramics and polymers
  • ‚‚ Patterning of complex nanostructures

Materials science

The powerful Xe plasma ion column makes XEIA3 the system of choice for the semiconductor and microelectronic industry. High currents for rough milling, ideal for lamella preparation or large cross sectioning; medium current for polishing and reducing surface artifacts (curtaining effect); small current for fine polishing of cross sections and lamellae. Ion lithography allows for better resolution in patterning.
