TREE NEWS update: GlobalFoundries said on October 8 it has signed a multi-year manufacturing agreement with TSMC worth about $2 billion to supply silicon interposers in the United States for TSMC’s CoWoS advanced packaging ecosystem. GlobalFoundries will expand capacity at its Malta, New York fab, becoming the first US supplier of silicon interposers for advanced packaging, including embedded deep-trench capacitor technology. Volume ramp is expected in the first half of 2028, with an initial five-year term.
GlobalFoundries, TSMC Sign $2B US Advanced Packaging Deal
The notable shift here is structural rather than financial: a foundry usually seen as a lagging-edge player is being folded into the leading-edge packaging supply chain, and the interposer — long an underappreciated chokepoint — is being localized on US soil for the first time. That matters most for AI accelerator customers dependent on CoWoS, who gain a second geographic source, and for GlobalFoundries' Malta site as it takes on a higher-value role. The open question is timing: with volume ramp only in the first half of 2028, this does nothing to ease near-term packaging constraints.
