United Microelectronics Corporation, Taiwan’s second-largest contract chipmaker, announced the first mass-production wafer delivery of photonic integrated circuits from its Singapore 12-inch fab on July 14. The wafers were built in partnership with SILITH Technology, a Singapore-headquartered fabless silicon photonics company whose 1.6T platform has already shipped more than 8 million 100G and 200G-lane PICs. The two firms took the platform from development to production readiness in 18 months, and a leading cloud infrastructure customer has already qualified it for volume deployment.
