UMC and SILITH have completed first mass-production delivery of silicon photonic wafers from a 12-inch fab in Singapore, moving the technology from lab demonstrations to industrial-scale manufacturing with predictable yield and cost. The platform supports 1.6Tbps optical interconnects for AI data centre use and reached customer qualification in 18 months.
This Wire brief sits within Fusion42's coverage of Semiconductors, Photonics & Optics and AI Infrastructure.
◆ ◆ The Wire takeaway
If you build optical modules for data centre interconnects, you now have a foundry that can deliver at volume and cost, not just samples. UMC's platform removes the manufacturing risk that has kept silicon photonics expensive—call them before your competitors do.
