Large Area Multilayer Deposition

The scia Coat 500 is used for homogeneous coating of large substrates for precision optics. Recipe controlled deposition processes allow a repeatable quality of multilayer stacks. Thereby, a changeable shaper system (up to 4 shapers) compensates parameter and/or material dependent inhomogeneity effects and enables the deposition of defined gradient films.

Features & Benefits

  • Excellent uniformity due to linear movement
  • Up to 6 water-cooled target materials on a rotational holder for in-situ change
  • Recipe controlled multilayer deposition with quartz crystal oscillator and/or optical thickness monitor (OTM)
  • Controlled movement of linear axis system for gradient coating or surface error correction
  • Optional substrate heating up to 250 °C to optimize film stress

Applications

  • Multilayer films for optical filters, X-ray mirrors and synchrotron mirrors
  • Optical coatings for high- and anti-reflective and dielectric layers
  • Deposition of films with property gradients (Göbel mirrors)
  • Ion beam smoothing
  • One-dimensional ion beam figuring
     

Application Note

Principle

  • Primary source sputters material from a target to the face-down oriented substrate
  • Secondary source used for pre-cleaning the substrate and/or assist during deposition

Technologies

Ion Beam Sputtering (IBS) thereby material is sputtered from a target with an ion beam and is deposited on the substrate.

Dual Ion Beam Sputtering (DIBS) uses an additional assist ion beam source to influence the growing film.

Ion Beam Etching (IBE) uses a collimated beam of inert gas ions for structuring or material removal.
