TSMC CoWoS interposers: GlobalFoundries’ 2028 plan
GlobalFoundries will produce silicon interposers for TSMC's CoWoS advanced-packaging system at its New York facility, starting volume production in early 2028. The five-year agreement aims to establish a U.S.-based source for these components, crucial for AI systems. TSMC will handle broader CoWoS offerings and finished-package integration.
