Rockley signs up to use SkyWater BEOL
US foundry SkyWater Technology has broadened its engagement with Rockley Photonics Ltd. (Oxford, England) to include back-end of line (BEOL) processing for Rockley's spectrophotometer-on-a-chip health monitor.

The expanded relationship with SkyWater is part of multi-sourcing efforts at Rockley. Rockley had a contract with Newport Wafer Fab to make silicon photonics but Newport Wafer Fab has been acquired by Nexperia, and renamed as Nexperia Newport. The emphasis going forward there is believed to be GaN-on-Si for power applications.

SkyWater provides R&D facilities for manufacturing processes, wafer fabrication and advanced packaging services.

"SkyWater provides us with a domestic U.S. source for advanced wafer-level components which is a critical part of our multi-source supply chain strategy. As we target high-volume consumer and industrial applications, deepening our connection with SkyWater is an important step in expanding our manufacturing ecosystem,” said Andrew Rickman, CEO and founder of Rockley Photonics, in a statement issued by SkyWater.

Thomas Sonderman, SkyWater CEO, said: "We're excited to be Rockley’s strategic supplier in the US to provide them with both front-end and back-end-of-line solutions to help Rockley bring its transformational technology to market."

While many of today's wearable consumer electronic devices use green light-emitting diodes to monitor heart rate, Rockley's infrared spectrophotometers can detect and monitor a much wider range of biomarkers, which could dramatically increase the functionality of wearable devices.
