  Plasma and Ion Sources >> Gridless Gas Ion Source

Gridless Gas Ion Source

The ion source is ideal for a wide variety of applications such as surface precleaning to enhance film/substrate adhesion, ion beam bombardment to improve film microstructures and properties, sputtering of different target materials for deposition, assisting film growth, and so on.   

Linear ion source

Circular ion source


  • ­Reactive gas compatible
  • ­Ion beam etching, cleaning and sputtering
  • ­Ion beam assisted deposition
  • Surface activation
  • ­In-situ ion beam pre-cleaning in a static processing system
  • ­Direct deposition of thin films (e.g., DLC using hydrocarbon based gases)
  • ­Industrial, low maintenance design
