TSMC signs $2 billion silicon interposer supply deal with GlobalFoundries
Taiwan Semiconductor Manufacturing Co. (TSMC) will buy silicon interposers from U.S. foundry GlobalFoundries for AI chip packaging. The contract is worth $2 billion and runs for five years, with mass production slated for the first half of 2028 at GlobalFoundries’ Malta, New York plant. The partnership is expected to accelerate TSMC’s U.S. advanced‑packaging rollout and free up its 12‑inch fab capacity for higher‑margin logic chips.
Why it matters
The company says the deal will free valuable fab capacity for higher‑value products and could move TSMC’s first U.S. advanced‑packaging plant forward to 1H 2028. Analysts note the agreement may ease U.S. pressure on TSMC’s supply chain and improve capital efficiency.
