Tescan TRUE X-Sectioning is a time-saving method for producing high-quality, ripple-free plasma FIB cross-sections, especially when working at large scales. When preparing cross-sections in the 100 µm to 1 mm range, traditional Pt deposition often becomes a major bottleneck: the protective layer must cover a wide and often uneven surface, requiring long deposition times and a thicker Pt cap to make the large topographic area more homogeneous. Even then, beam-induced rippling often persists, forcing users to drop the beam current and significantly extend milling times.
TRUE X removes this limitation by replacing slower in-situ deposition with pre-cut monocrystalline silicon masks that can be positioned and attached to the sample surface using the Tescan Nanomanipulator. These Si masks provide a perfectly stable, uniform protective layer that tolerates even the highest plasma FIB beam currents, enabling fast, ripple-free milling on hard, composite, and resin-embedded samples. A guided workflow in Tescan Essence™ assists with mask selection, placement, and attachment - ensuring consistent, high-quality cross-sections with minimal operator effort.
