IBD2

General Information and Usage:

This tool is designed for high quality, precise, reproducible deposition of dielectric films for optical quality films. Metallic material is ion bombarded from a target material and a reactive ion beam of oxygen and/or nitrogen is aimed at the surface, creating a metal-oxide or nitride on the sample.The system is fully computer controlled to facilitate multi-layer stack recipes for high reflectivity or low reflectivity coatings.Current available targets are Ta and Si, with Al and Ti to be added soon.The system is load locked and can handle wafers up to 6” in diameter as well as small pieces. Sample rotation and angling is used to facilitate material quality and allows for sidewall coverage on non-planar surfaces. Uniformity is better than 2% over 4" wafers and reproducibility is expected to be within one percent.

 

Detailed Specifications:

  • Xenon target bombardment
  • Nitrogen and/or Oxygen deposition assist source for metal oxides/nitrides
  • Ta and Si targets (Al and Ti coming soon)
  • Pieces up to 6” wafers accepted
  • Full programmable control through GUI for multi-layer optical coatings
  • Ta2O5 (1.33 A/s rate) and SiO2 (0.85A/s)characterized, standard recipes
  • Base Pressure ~ 3e-8 Torr
  • High quality, high reflectivity (>99.5%) mirrors demonstrated in blue wavelengths
