Semicon Briefing

ON Semiconductor acquired Synaptics in June 2026, expanding its AI datacenter power management line – supplemented by the Vcore Power Technologies IP deal closed on September 23rd. The pattern demonstrates a targeted consolidation strategy for AI infrastructure components, positioning onsemi as a key player in datacenter power delivery.

TSMC plans pilot production on the 1.4-nm node as early as Q1 2027, while Samsung risks falling structurally behind its rival. Analysts see a potentially sustained technological advantage for TSMC that could shift large fabless customer orders in Taiwan's favor for years to come.

Belgian research institute imec is expanding access to TSMC's advanced nodes for ASIC and silicon photonics designs via its IC-Link platform. The collaboration lowers entry barriers for smaller chip developers and accelerates commercialization of optical interconnects for AI systems.

The US Department of Defense is investing $174 million in an Australian gallium production facility jointly with Japan's Sojitz to counter China's export restrictions on chip-critical minerals. Gallium is essential for compound semiconductors in radar, 5G, and RF chips – control over these precursor materials is becoming a new geopolitical pressure point.

An investigative NYT report documents that US-sanctioned Chinese companies continue to acquire export-restricted Nvidia chips through third-party markets despite existing controls. The disclosure increases pressure on Washington to significantly tighten end-user verification systems and jeopardizes the credibility of the entire US export control regime.

Following the sale of its sensor division to Infineon, ams-OSRAM has signed a development contract with an unnamed leading AI infrastructure player for its new 32-Gb/s microVCSEL. This positions the company as a key supplier of optical high-speed interconnects for AI datacenters – a market segment with exponential growth potential.
