Semicon Briefing

ON Semiconductor has announced the largest acquisition in its history: $7B for Synaptics to enter the Physical-AI segment. The deal triggered a sharp stock decline – investors doubt whether Onsemi can manage the $200M synergy plan and simultaneous growth in still immature AI markets.

SiTime has officially completed the acquisition of Renesas Electronics' timing business, strengthening its position as a leading provider of MEMS timing solutions for data centers and AI infrastructure. The closing signals that consolidation pressure in the semiconductor supply market continues to increase.

South Korea's government has agreed with Samsung and SK Hynix on an 800 trillion won investment package that includes four new fabs and dedicated HBM facilities – as a direct response to the global AI memory shortage. Applied Materials and ASML subsequently recorded record share prices as analysts expect massively increasing equipment demand.

Infineon's new Smart Power fab in Dresden went into operation three months ahead of schedule and is the first concrete success of the EU Chips Act with approximately €1B in subsidies. The fab produces power semiconductors for AI data centers, electric vehicles and renewable energies, and noticeably strengthens Europe's semiconductor sovereignty.

The stealth startup Substrate, backed by Peter Thiel, promises a revolutionary X-ray lithography platform as an alternative to ASML's EUV technology and faces an installed EUV base worth over $1 trillion. Experts are skeptical – EUV took decades to mature – but the discussion alone shows that the market is seeking strategic alternatives to the ASML monopoly.

TSMC and Amkor Technology have announced a long-term partnership to accelerate advanced packaging in the US, which should further deepen the domestic supply chain for AI chips. The move complements TSMC's Arizona fab expansion and is likely to increase pressure on competing packaging providers.
