More specific materials

Classical dry etch or IBE for all above

Ion Beam Etching

FIB cut
FIB cut
  • Etching for up to 4µm thick layers
  • Some material expamples: NiFe, Au, Ag, Pt, PZT, KNN, TaN, TiN, LNO

Multi Source Sputtering

Special tool for foundry topics

Additionally to the full production sputter processes, we can offer a multisource chamber.

Capability of co- and multilayer-sputtering with 4 x 100 mm targets (we can deposit almost „everything“)

  • Low deposition rate but capability of controlled deposition of ultra thin layers <1nm
  • Mainframe:
    • 4 single source sputter modules: Ti, Ag, Al/AlOx (reactive), AlCu
    • Peripheral modules: softetch; cooler; degas
    • Attached to mainframe :1 multi source sputter module
  • 2 x RF- and 2 x DC- sources
  • Ar + N2 +O2
  • Tw,max > 500°C
  • Rotating chuck
  • Wafer shutter and source shutter

Currently available targets:

  • Ag, Al, Al2O3, Au, Cr, Cu, Ge, Mo, NiCr, Ru, Si, Ti, W
