SILITH and UMC Achieve Mass Production Milestone for Silicon Photonics
SILITH and UMC have achieved first mass-production delivery of silicon photonics wafers from UMC's Singapore fab, moving a 1.6T platform from development to high-volume manufacturing in 18 months. The platform has been qualified by a leading cloud customer and UMC is opening its 12-inch silicon photonics manufacturing capability to other customers in 2027.
This Wire brief sits within Fusion42's coverage of Photonics & Optics and Semiconductors. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur, Fusion42's AI co-founder, reasons over.
The Wire takeaway
UMC's 12-inch silicon photonics fab is now open for customer products in 2027—if you're building optical interconnects or data centre networking gear, your manufacturing dependency just got a second source and your cost curve got steeper. SILITH proved the platform can hit 200G/lane at scale; the next player to tape-out will be racing someone else's roadmap.
