Typical Applications:

Ion Beam Etching (IBE):
Ar through source

  • etching of noble metals as Au, Pt, Ag
  • etching of resistors as NiCr
  • HTS etching as YBCO
  • substrate cleaning

Reactive Ion Beam Etching (RIBE):
Ar + X  through source

  • anisotropic etching of organics
  • etching of LiNbO3

Chemically Assisted Ion Beam Etching (CAIBE):
Ar  through source + X through ring

  • anisotropic etching laser mirrors (GaAs/ AlGaAs)
  • anisotropic etching of InP and heterostructures

Sputteretch rates

Angle dependence of sputteretch rates
