Ion Beam Etching (IBE) Solutions

Ion beam technology provides an exceptionally versatile approach to etching by offering a single tool and maximising system utilisation. Ion beam etch offers maximum flexibility coupled with excellent uniformity.

Ion Beam Etching (or milling) is achieved by directing a beam of charged particles (ions) at a substrate with a suitably patterned mask in a high vacuum chamber. It enables highly-directional beams of neutral ions to control over the sidewall profile as well as radial uniformity optimisation and feature shaping during nanopatterning.

Tilted features can be created by the unique ability to tilt the sample altering the direction of impact of the ion beam.

Our ion beam system, Ionfab, can be configured for etching (IBE) as well as deposition (IBD) technologies.

Key Benefits of IBE

  • Allows beam energy and ion flux to be independently controlled
  • Process takes place in a low-pressure working environment
  • Produces anisotropic etching
  • Provides means for all known materials to be etched
  • Allows angled profile control thanks to a variable etch beam angle relative to sample/mask surface
