EV Group has said it is partnering with DELO to expand materials and process capabilities for wafer-level optics (WLO) and nanoimprint lithography (NIL).

The two companies are combining efforts to develop optical devices and applications, such as biometric authentication and facial recognition, for the industrial, automotive and consumer electronics markets using EVG’s leading lens moulding and NIL process equipment and DELO’s advanced adhesives and resist materials.

The partnership will contribute to improving and speeding up material development cycles. Advanced adhesives and resists play a pivotal role in enabling wafer-level production of next-generation optical sensors for mass markets. The development of advanced optical materials requires extensive characterisation of chemical, mechanical and optical properties as well as proven scalability for high-volume manufacturing (HVM). Knowledge of material requirements for automated moulding and demoulding processes, as well as excellent material compatibility of working NIL stamps and resists, are important as they enable optimal WLO performance at the smallest form factors using proven HVM processes.

Similarly, close collaboration between materials suppliers and process equipment manufacturers is key to enabling the development and refinement of processes needed to ensure high reliability and manufacturability of WLO for high-quality products.

As such, this joint effort between EVG and DELO will support both companies in refining their processes and products, as well as strengthening their expertise to address current and future market requirements.

“EVG and DELO are known as technology and market leaders in WLO and NIL equipment and, respectively, optical materials, with a proven track record in ramping these technologies and processes into high-volume production,” commented Robert Saller, managing director at DELO. “Together we can provide unique know-how in applying wafer-level processing technology to optical and photonics manufacturing, making EVG an ideal partner in the development of our latest products. This collaboration will in turn help us to serve our customers as an application expert and premium partner.”
