GlobalFoundries and TSMC Join Forces in $2 Billion Deal to Bring Advanced Packaging Components to the United States

In a significant move to bolster the domestic semiconductor supply chain and expand advanced manufacturing capabilities within the United States, foundry giants GlobalFoundries and Taiwan Semiconductor Manufacturing Company (TSMC) have entered into a major five-year manufacturing agreement valued at $2 billion. Under the terms of the newly minted partnership, GlobalFoundries will produce critical silicon interposers designed to support TSMC’s industry-leading Chip-on-Wafer-on-Substrate (CoWoS) advanced packaging technology.

The strategic arrangement is designed to establish a reliable, U.S.-based manufacturing source for these indispensable semiconductor components. By localizing a key element of the advanced packaging workflow, the partnership will effectively enable TSMC’s diverse roster of clients to brand their finished microelectronic products as completely made and packaged in America. This capability addresses a long-standing bottleneck in the domestic tech hardware ecosystem, where advanced manufacturing has historically been heavily concentrated overseas, particularly across East Asia. According to the project roadmap, volume production for the silicon interposers is scheduled to ramp up steadily, with commercial output expected to officially kick off in the first half of 2028.

The collaboration brings together two of the most influential players in the global semiconductor landscape, combining TSMC’s dominant position in advanced logic manufacturing and packaging innovation with GlobalFoundries’ extensive, secure manufacturing footprint within the United States. Industry analysts note that advanced packaging technologies, such as CoWoS, have become the cornerstone of modern high-performance computing, artificial intelligence accelerators, and data center hardware. Because these modern processors require multiple chiplets to be tightly integrated onto a single interposer to communicate at blazing speeds, securing a resilient and geographically diverse supply chain for interposers is paramount to meeting surging global demand.

Executive leadership from GlobalFoundries emphasized the strategic importance of the collaboration not only for the two companies involved, but for the broader technology sector and national industrial resilience. "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," said Ed Kaste, senior vice president of CMOS Business at GlobalFoundries. His remarks underscore the growing urgency across the technology industry to establish domestic redundancies and secure fabrication pathways that are less vulnerable to geopolitical tensions, supply chain disruptions, and logistical bottlenecks.

The integration of GlobalFoundries into the CoWoS supply chain represents a major milestone for the domestic production of cutting-edge hardware. As artificial intelligence workloads continue to drive unprecedented requirements for processing power and memory bandwidth, the demand for advanced packaging capacity has frequently outstripped supply across the globe. By establishing a domestic pipeline for silicon interposers—the foundational layer upon which advanced multi-die processors are assembled—this $2 billion agreement lays the groundwork for a more self-reliant semiconductor ecosystem in the United States. As the industry looks toward the targeted 2028 volume production ramp-up, stakeholders across the technology sector will be closely monitoring how this high-stakes partnership reshapes the future of domestic hardware manufacturing and packaging.
