Grating Foundry Services

Ibsen offers a variety of grating foundry services

Holographic or Lithographic pattening and
RIE/ICP etch

We offer pattening and etch of grating structures on fused silica or other materials, applying Ibsen’s unique know-how:

  • 100% Class 10 cleanroom environment
  • Grating period accuracy and uniformity of +/- 0.01 nm
  • Substrate / wafer size capabilities up to 6″ (150 mm)
  • Grating area definition possibilities
  • RIE etching services combined with the grating patterning service

We have holographic stepper and lithography based production equipment for cost-effective, high volume production of gratings with sizes up to approx. 25 mm x 20 mm, and we have flexible, low volume holographic production equipment for gratings up to 120 mm size. A couple examples of gratings patterned in photoresist are shown below.
