idonus VPE product

Very high aspect ratio structures etched in silicon are desired in many microtechnology applications. Exploring a new process of metal assisted chemical etching in hydrofluoric (HF) acid vapor phase for the fabrication of nanowires and X-Ray optics, our partners at Paul Scherrer Institute (PSI) have published some impressive results in Nanoscale Horizons:

  • 10-100 nm nanowires
  • more than 100 ┬Ám length
  • ultra-high aspect ratio (10'000:1)
  • linear and circular gratings for X-Ray optics

The process uses idonus HF Vapor Phase Etcher (VPE) and opens possibilities for a whole new range of applications. Used by many research institutes and MEMS fabrication facilities around the world, HF Vapor Phase Etcher is one of the most versatile, cost-effective and safe equipment of its kind on the market.
