Large Area Dry Etching of Slanted Gratings for Augmented Reality Applications

25 June 2020 at 3PM (BST)


About the Webinar

This webinar will give you an insight into the latest advancements at Plasma Technology on dry etching slanted features for Augmented Reality.

Waveguide combiners based on slanted gratings are a technology of choice to demonstrate high efficiency for in grating coupler. However, there are numerous challenges in their manufacturing process.

In this webinar, we discuss one of the most mature manufacturing approaches based on stamping. We'll explain how we have developed a solution for 45 degree angled features on a 200mm wafer area.

In this webinar, you will learn:

  • How to manufacture slanted grating for Augmented Reality using the Oxford Instruments IonFab® system
  • How to control critical gratings parameter to maximise yield on large wafer size
  • Best practises to demonstrate tight control of manufacturing tolerances
