TSMC to source silicon interposers in US under $2b deal with GlobalFoundries
TSMC will source silicon interposers from GlobalFoundries (GF) in the US under a $2 billion deal. GF will expand its New York factory to supply TSMC, with production starting in 2028. Silicon interposers are critical for AI chip manufacturing and have been a supply bottleneck. GF's US production will be the first for this component, potentially pressuring memory chip suppliers to localize.
