Raith150 Two Ultra-High Resolution Electron Beam Lithography and Imaging

Since its launch, the RAITH150 Two has proven itself as a winner among universal, high-resolution electron beam lithography systems. This advanced solution is used in research and nanotechnology centers around the world and has established its robustness in 24/7 use.

The RAITH150 Two is designed to expose structures smaller than 5 nm and can handle sample sizes ranging from a few mm to 8″ wafers.

The stability of the RAITH150 Two, even in tough environments, required for challenging exposures is made feasible by an environmentally tolerant and thermally stabilized shield.

Ultra-High Resolution and Imaging

  • Sample handling up to 8"
  • Sub 8 nm lithography
  • System automation
  • Split room setup/thermo stabilization
  • Low kV exposure and imaging

Pure Research and Small Batch Production

Hardware and software automation enable effortless and repeatable tasks for small-batch production.

The RAITH150 Two high-resolution electron column along with a range of detectors facilitates unparalleled flexibility in process control and mark recognition.
