A $2 billion agreement for U.S.-made interposers
GlobalFoundries announced on October 8, 2026, that it will manufacture silicon interposers for TSMC’s CoWoS advanced-packaging ecosystem at its Malta, New York, facility. The companies describe the multi-year agreement as worth $2 billion. Under its terms, GlobalFoundries will provide manufacturing services to TSMC and add fabrication capacity at the site, supporting demand for high-performance computing and AI systems.
The deal makes GlobalFoundries a U.S.-based supplier of a component used in TSMC’s packaging system, rather than a producer of TSMC’s packaged chips. The announcement says the new capacity will support demand for high-performance computing and AI systems. It does not break down the $2 billion by investment, production volume or payment schedule, so the headline figure does not specify how much capacity the agreement will fund or how payments are structured.
Malta production is expected in 2028
GlobalFoundries expects volume production to begin ramping at its Malta facility in the first half of 2028. The agreement has an initial five-year term and provides a framework for future capacity expansion as customer demand grows, the company said. The release does not provide a target for wafer output or identify specific customers for the additional capacity.
The company says the expansion will establish the first U.S.-based source of silicon interposers supporting advanced-packaging technologies, including embedded deep-trench capacitor components. It expects the added manufacturing capacity to provide greater scale and flexibility for delivering advanced-packaging solutions across multiple product generations. The announcement describes capacity growth over time, but does not give a production-volume target or a schedule for later expansion beyond the initial ramp expectation.
The stated production milestone is a forecast, not a report of current output: volume production is expected to begin ramping during the first half of 2028. The release also frames future capacity increases as dependent on customer demand. It gives the agreement a five-year initial term while leaving open a framework for expansion, without specifying the scale or timing of any later additions.
Why the packaging supply matters to AI systems
GlobalFoundries’ announcement ties the agreement to the growing need for advanced packaging in AI and high-performance computing. The company says silicon interposers and related components will serve TSMC’s CoWoS ecosystem, while adding a domestic manufacturing source. It does not describe how much of TSMC’s overall interposer demand the Malta site is expected to meet.
“Advanced packaging is becoming increasingly critical to delivering the performance, power efficiency and scale required for next-generation AI systems,” said Ed Kaste, senior vice president of CMOS Business at GlobalFoundries. “By providing manufacturing service using GF’s trusted U.S. manufacturing footprint, we are creating a secure, scalable source of essential advanced-packaging elements that will help customers accelerate innovation and strengthen the semiconductor supply chain.”
GlobalFoundries says the added capacity is intended to support advanced-packaging solutions across multiple product generations. The announcement does not quantify the share of CoWoS demand that the Malta facility could supply, or set out details such as output volumes. Its focus is the manufacturing arrangement and the planned U.S. source, rather than a forecast of the agreement’s contribution to TSMC’s total packaging capacity.
A five-year framework, with capacity still to come
The agreement gives TSMC access to manufacturing services from GlobalFoundries at a U.S. site and gives GlobalFoundries a defined role in the packaging supply chain. But the release leaves several commercial details undisclosed, including how the $2 billion is allocated and how much capacity the facility will add. Its clearest near-term milestone is the planned volume-production ramp at Malta in the first half of 2028.
