Light Enables Light - How to Reliably Produce VCSEL Devices
Augmented Reality is a relatively new technology that allows users to visualise and interact with computer-generated objects layered on top of real-world environments. Also known as mixed reality (MR), AR requires an optical combiner which allows the eye to see the real-world whilst projecting a virtual image. Its main uses are in manufacturing and video gaming but AR technology is also being deployed for training, security and surgical procedures.
For optimum optical performance, surface relief gratings based AR combiners must be manufactured with both an excellent CD and profile control as well as excellent angle control. This can be achieved through mask dry etching and angled grating etching processes.
For more information on how Augmented Reality works, take a look at our blog.
Augmented Reality has several applications, with many currently in the research & development phase. Hololens from Microsoft and Magic Leap One by Magic Leap are part of the smart glass market, which is on-trend to be highly-popular in the near future. Many business-to-business (B2B) applications are now common too, with uses in construction and computer-aided design.
Whilst many technologies have been considered to deliver truly immersive AR experience, the waveguide approach has been favoured by major players such as Microsoft Hololens and Vuzix because of its ability to achieve a high field of view.
We have many years of expertise in etching the slanted feature on large areas. Our solutions are designed to deliver the manufacturing quality required for surface-relief gratings. We support manufacturers in reaching optimum optical efficiency with a range of slanted angle available. Over the years we have continuously improved our solutions for etching slanted features and we are now offering market-leading uniformity wafer sizes of 200mm and up.
Our advanced plasma processing solutions – achieved with ICP Etching, RIE and Ion Beam Etching – can handle wafers up to 200mm in size for high-volume production of AR devices. Our Ionfab system for IBE has been configured for optimum uniformity on 200mm wafer size. Our proprietary ion beam technology and patented grid design allow us to produce standard 45° gratings with excellent precision. Our processing capability covers various materials such as Si and SiO2.
Cluster configuration options are available, using a field-proven, highly-reliable vacuum transfer robot for mask etching and AR coating modules.
