GlobalFoundries Signs $2 Billion TSMC Deal to Build AI Chip Packaging Components in New York
GlobalFoundries said Thursday it will produce silicon interposers for TSMC under a $2 billion, five-year deal at its Malta, New York facility, a pact the company said would create the first U.S. source for the advanced-packaging component.
GlobalFoundries said Thursday it will manufacture silicon interposers for Taiwan Semiconductor Manufacturing Co. at its Malta, New York, facility under a $2 billion, five-year agreement, a deal the company said would establish the first U.S.-based source of the component used in advanced AI chip packaging.
A silicon interposer sits beneath AI processors and high-bandwidth memory chips inside an advanced package, allowing the parts to communicate at high speed. The component is a key element of TSMC’s Chip-on-Wafer-on-Substrate packaging, which links processors to memory in systems built for artificial intelligence workloads.
Volume production set to ramp in 2028
Under the agreement, GlobalFoundries will expand capacity at the Malta plant to produce the interposers, including embedded deep trench capacitor components for demanding computing applications. Volume production is expected to begin ramping up in the first half of 2028, and the framework allows for further capacity expansion as demand grows, according to the company.
Shares of GlobalFoundries rose about 4% in premarket trading on Thursday after the announcement, according to Reuters, and climbed nearly 6% in morning trading, according to Stocktwits.
Packaging bottleneck shapes the AI buildout
Advanced packaging has become a central constraint on AI chip production, as demand for the technology has outpaced available capacity. Industry research firm Counterpoint has estimated the supply-demand gap for TSMC’s CoWoS capacity could remain near 20% in 2026 before narrowing to about 10% in 2027 as more capacity comes online, according to Stocktwits.
TSMC reported third-quarter revenue of about $46.71 billion on Thursday, up 50% from a year earlier, with September revenue of about $16.03 billion. For GlobalFoundries, the pact expands its role in the AI supply chain while adding advanced-packaging manufacturing in the United States.
