Semicon Briefing

Samsung and AMD have signed a Memorandum of Understanding for HBM4 supply for MI455X GPUs and DDR5 for 6th-Gen EPYC CPUs – complemented by explicit exploration of a foundry partnership. The deal signals that AMD wants to strategically reduce its TSMC dependency and positions Samsung as a serious foundry challenger.

Following the Supermicro smuggling case (2.5 billion USD Nvidia hardware to China), US senators called on a bipartisan basis for the immediate suspension of all Nvidia export licenses to China and parts of Southeast Asia. In parallel, three additional individuals were charged with attempted sanctions evasion – enforcement pressure on chip exports escalates to a new level.

STMicroelectronics has joined forces with Infineon and NXP in a cooperation with Nvidia announced on March 17, 2026, to develop system architectures and AI processors for humanoid robots. The alliance of European and American chip companies underscores that the robotics market is becoming the next strategic growth frontier for the semiconductor industry.

The US State Department launches the 'Pax Silica' fund with 250 million USD initial capital, which is designed to leverage up to 1 trillion USD in private capital for critical minerals and chip manufacturing. The initiative complements the CHIPS Act and aims to actively secure geopolitically exposed supply chains – a direct signal to China and allies.

TSMC's fourth Arizona fab is already completely pre-booked before construction officially begins – Apple, Nvidia, AMD, and Qualcomm are securing US capacity. This demonstrates extreme demand for onshore chip production and increases pressure on Intel and Samsung to accelerate their own US presence.

Tower Semiconductor acquires complete control of the 300mm fab in Uozu, Japan, and announces a quadrupling of 300mm capacity – a rare, concrete expansion step in a tight capacity environment. The move strengthens Tower's position as a specialist in analog and mixed-signal chips and should alleviate supply chain pressure for automotive and industrial customers.
