SOLAYER announced Dec. 17, 2020, the development of a near-infrared bandpass filter (NIR BPF) with superior filtering characteristics, enabled by novel "zero-bow" technology for thin glass substrates on the AVIOR M-300 vacuum coating system. SOLAYER develops high-performance manufacturing equipment and processes for the mass production of high-quality functional coatings, especially optical coatings.
The new X41 filter enables 3D sensors used in consumer electronics, automotive, security and other applications. This development highlights the special features of this SOLAYER technology, solving an inconvenient technical problem (bent wafers) and providing manufacturers with a viable solution for producing high-quality NIR BPFs.
SOLAYER has developed its unique "zero-bow" technology for ultra-thin glass substrates (0.2 mm thickness), enabling customers for the first time to apply wafer bonding technology to high-performance NIR BP filters. Key applications include:
- Advanced sensor technologies
- Mobile gesture recognition technology
- Automotive applications (TOF, LIDAR).
SOLAYER's "Zero-Bow" technology for NIR-BP filters on very thin substrates brings significant benefits to customers:
- Reduced complexity in subsequent process steps
- Higher yield in production and simplification of downstream processes
- Enables transition to wafer bonding technologies
SOLAYER's CEO Mathias Höfler emphasized the company's goal of helping manufacturers trigger new waves of product innovation. Overcoming the technical bottlenecks created by curved wafers is key to this effort. "The X41 filter, enabled by our "zero bow" technology, demonstrates the endless possibilities, and we are excited to provide this technology and related expertise to our customers."
