GlobalFoundries signs $2 billion five‑year deal to produce silicon interposers for TSMC

GlobalFoundries will manufacture silicon interposers for TSMC’s CoWoS advanced‑packaging system at its Malta, New York plant. The agreement is valued at $2 billion over five years and calls for volume production to start in the first half of 2028. The deal creates a U.S.‑based source of these critical components for AI and high‑performance‑computing chips. Capacity will be expanded at the New York facility and the contract includes a framework for future expansion.

The company says the $2 billion agreement represents roughly 5.6 % of GlobalFoundries’ 2026 annualized revenue, providing a material near‑term revenue boost. For TSMC, the deal secures a domestic supply of interposers, reducing reliance on overseas packaging and strengthening its U.S. supply chain.
