High Quality Cleaning and Qualification up to 800 mm in dia. and 500 mm in height

The scia Clean 800 is used for dry cleaning of 3 dimensional shaped substrates with weights up to 500 kg. The chamber design and functionality ensures a very good base pressure and allows to quantify even small residual contaminations on the substrate by mass spectroscopy measurement.

Features & Benefits

  • Low base pressure and fast pumping due to electro-polished and heated vacuum chamber
  • Separate substrate heating for improved desorption
  • Qualification of residual contamination by high sensitive mass spectroscopy
  • Optional plasma source for advanced cleaning with H2 plasma
  • Recipes for repeatable temperature ramps and fully automated cleaning cycles
  • Crane for loading of large and heavy substrates

Applications

  • Ultra-high purity cleaning of X-ray optics
  • Cleaning of components for beam line accelerators
  • Outgassing qualification of complex vacuum assemblies

Principle

  • Dry Cleaning
    • Removing of contamination from the 3-dimensional shaped substrates by using ultra high vacuum
      (vacuum desorption)
    • Further cleaning progress with optional heating of the substrate and/or chamber (thermal desorption) and applying plasma treatment
