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.

  • Fast, Ripple-free large-area cross-sectioning, even above 500 μm, using robust monocrystalline silicon masks instead of thick Pt deposition


  • Easy to use thanks to guided workflow in Tescan Essence™ covering mask placement, attachment, milling, and removal


  • Extensive library of 900+ pre-cut Si masks in multiple widths for broad sample and geometry compatibility

Where Tescan TRUE X-Sectioning Makes the Difference

Ripple suppression on large (up to 1 mm) and complex surfaces

Pre-cut monocrystalline Si masks provide a rigid, uniform protective cap that eliminates ion-beam–induced ripples on surface finishes of hard, composite, or resin-embedded samples—even when cross-sections reach 1 mm and Pt deposition would require excessive time and thickness. 

High-current plasma FIB performance without surface damage

TRUE X-Sectioning enables meaningful utilization of the highest plasma FIB beam current for fast material removal while still producing smooth, artifact-free cross-sections. Tescan True X-sectioning can be also combined with the Tescan Rocking Stage enabling even faster, clean large-area cross-sections and FIB-SEM 3D tomography results.

Optimized protection for any cross-sectional requirements

The TRUE X-Sectioning package includes over 900 pre-cut Si masks in multiple sizes, allowing users to select the ideal mask for their specific requirements on milling scale or surface characteristics.

Fast, guided mask placement with minimal operator effort

The Mask Placement Wizard in Tescan Essence™ leads users step-by-step through mask positioning, attachment, milling, and removal. Workflow can be completed in minutes and delivers highly repeatable outcomes..

Advanced Performance
