TSMC is accelerating its advanced packaging roadmap for AI chips, expanding CoWoS capacity while publicly disclosing new progress in glass substrate technology. The company is also signaling that next-generation packaging competition is shifting from CoWoS toward CoPoS as it builds out a fuller ecosystem ahead of rivals.

China has recently eased controls on some indium phosphide (InP) substrates, relieving a bottleneck in optical communications capacity for the second half of the year. But supply chain players say the long-term priority is still to expand substrate capacity from non-China sources, with supply security for the AI industry outweighing price.

A South Korean media report claiming TSMC is preparing to launch panel-level packaging at mass-production scale as early as 2027 has drawn skepticism from Taiwan industry sources, who say the timeline is likely premature and that the company remains focused on evaluating multiple advanced-packaging options.

The semiconductor supply chain is facing another raw material shock — this time from tungsten hexafluoride, or WF6, a specialty gas used in chip manufacturing. Planned production adjustments or exits by some Japanese suppliers in the second half of 2026 have intensified concerns over tighter global supply, sending prices sharply higher and raising the risk of disruption into 2027.

Japan's Rapidus has signed a memorandum of understanding with the UK Semiconductor Centre, a government-backed body established in 2025 to support Britain's semiconductor ecosystem, marking a step toward cooperation on future semiconductor manufacturing and potential customer development in the UK, according to Rapidus and reports from Nikkei, Bloomberg, and Reuters.
