Semicon Briefing

GlobalFoundries signed a multi-year $2-billion contract with TSMC on October 8, 2026 to manufacture silicon interposers for TSMC's CoWoS packaging – a strategic step to close the US advanced packaging gap. The deal significantly strengthens the US manufacturing base for AI chips and reduces dependence on Asian suppliers.

The US announced new, stricter export restrictions for AI chips (NVIDIA, AMD, high-performance GPUs) against China, going beyond previous measures. This escalates the tech trade war immediately before the expiration of both moratoriums on November 10 and significantly increases pressure on ongoing US-China negotiations.

Huawei's management claims to have built a near-complete independent supply chain for chips since US export controls began in 2019. This statement, shortly before the expiration of US-China moratoriums on November 10, signals that China's semiconductor resilience has advanced further than previously assumed.

Infineon Technologies has officially completed its acquisition of C2i Semiconductors, expanding its innovation capabilities in AI data center energy management. The deal follows the €570-million ams OSRAM sensor division acquisition completed in July and demonstrates Infineon's consistent realignment toward AI infrastructure and power management.

ON Semiconductor announced the acquisition of Synaptics Incorporated on October 2, 2026, further intensifying the ongoing consolidation wave in the semiconductor sector. Combined with the completed Skyworks-Qorvo merger (>$500 million synergies), this demonstrates accelerated market consolidation among specialized chip providers.

TSMC's $165-billion investment in its Arizona GigaFab is progressing, with the CHIPS Act estimated to have accelerated implementation by two to three years. The project is considered the largest private semiconductor investment in US history and is a central element of the Western chip sovereignty strategy.
