White haired stock god calls out XFAB: European silicon photonics foundry layout core, may challenge TSEM and GFS, commercialization is still in the early stage BlockBeats News: On June 11th, Serenity, the "white haired stock god," announced that X-FAB Silicon Foundries SE (XFAB) is building a Silicon Photonics foundry replacement capability, which is seen by some market participants as a potential long-term competitor to Tower Semiconductor and GlobalFoundries, and may participate in Europe's layout in the CPO and photonics chip supply chain. X-FAB has currently received a certain degree of support from the European industry and is related to NVIDIA's technology evaluation system. Its development direction is interpreted as part of Europe's efforts to promote the independence of advanced packaging and silicon photonics supply chains. In terms of timeline, this statement indicates that the project development is still in the early stages, and it is expected that the development work may continue until around October 2026, followed by a gradual capacity introduction phase in 2027, and a larger scale production cycle may only begin around 2028, with the research and development starting roughly in 2023. At present, the market may still generally consider it as a traditional industrial or automotive supply chain related enterprise, but some views believe that its potential long-term value in the direction of silicon photonics and CPO has not been fully priced. However, this logic still heavily relies on the actual implementation progress of future technology commercialization, and overall it is still an early expectation driven narrative with high uncertainty.
