Advanced Wafer Coatings

The scia Magna 200 is used for precision wafer coatings by deposition of metals and/or dielectric layers. With its selectable sputter modes and arrangements the system can be configured according the customer requirements. In addition, the system is suitable for small scale R&D applications as well as for mass production, in cluster layout with software controlled automatic production.

Features & Benefits

  • RF bias for conformity and stress control
  • Superior uniformity with rotatable substrate holder
  • Low substrate temperature with helium cooling contact and electrostatic chuck
  • High deposition rates with reactive sputtering in unipolar and bipolar mode
  • Variation of film properties by adjustable energetic substrate bombardment
  • Co-sputtering with confocal arrangement of magnetrons

Applications

  • Temperature compensation films for TC-SAW devices (SiO2)
  • Piezoelectric films with excellent and defined crystal orientation (AlN)
  • Optical high- and low- refractive coatings (SiO2, TiO2, HfO2, ZrO2, Nb2O5 , Ta2O5)
  • Electrical insulating films (Si3N4, SiO2, Al2O3)
  • Co-sputtering of metals and alloys
     

Application Note

Principle

  • Magnetron Sputtering in several configurations:
    • Single magnetron with rotating magnetic field, magnetron dia. > substrate dia. (see video) or
    • Up to 4 magnetrons in confocal arrangement, magnetron dia. < substrate dia. (rotation required) or
    • DRM 400 from Fraunhofer FEP with two concentric targets, magnetron dia. > substrate dia.
       

Technologies

Magnetron Sputtering utilizes plasma ion bombardment on a target to deposit thin films on the substrate surface.
