Tescan has introduced Triglav a ultra-high resolution (UHR) electron column technology with significant improvement in quality imaging and analytical capabilities.

The Triglav column – equipped with unique electron optics and a robust detection system – achieves uncompromised ultra-high resolution for resolving nano-sized features in samples and provides enhanced surface sensitivity and image contrast at low beam energies.

Statement of Jaroslav Jiruše, Head of Research and Development
“We have completely redesigned our UHR column improving the resolution by 30%, achieving sub-nanometer resolution of 0.7 nm at 15 keV and an impressive 1 nm at 1 keV. In addition, the analytical potential has been significantly improved resulting in an excellent performance in the field-free mode. The Triglav column is based on the three objective lenses whose combination results in different imaging modes. The column is equipped with a universal detection system consisting of multiple SE and angle-selective BSE detectors for maximum surface and compositional contrast. Furthermore, the geometry of the column has also been redesigned allowing larger samples to be analyzed; this is particularly relevant to the semiconductor industry as large wafers can be accommodated for their analysis.”

UHR imaging is an essential capability for the semiconductor industry and is critical in performing routine root failure analysis in state-of-the-art technology nodes and multi-layered optical devices, or, defect characterization on wafers at known locations. In materials science, the characterization of nanowires and nanotubes is a challenging task that requires UHR in order to resolve the features of interest in such materials. UHR allows researchers to examine the detail of the ultrastructures of cell and tissue biology. While the outstanding imaging capabilities of the Triglav column excel in the entire range of accelerating voltages, it is the ultimate resolution and performance at low beam energies that makes this column ideal for imaging nonconductive and beam-sensitive samples.

The new UHR column technology is now an integral part of the Tescan UHR family systems – model 2016: MAIA3 a UHR SEM, and, GAIA3 and XEIA3 both FIB-SEM systems equipped with Ga and Xe plasma ion source FIB column respectively.
