TSMC accelerates glass substrates as Korea risks losing AI packaging lead - CHOSUNBIZ - Chosunbiz

Taiwan Semiconductor Manufacturing Company (TSMC) has disclosed verification results for glass substrates, signaling a strategic acceleration in next-generation semiconductor packaging. These substrat... Read original →

TSMC’s acceleration of glass substrate validation is a strategic move to lock in AI packaging leadership. Superior thermal stability and coplanarity enable larger, denser CoWoS interposers, forcing upstream suppliers like Ibiden to refine TGV processes. Korean players—Samsung Electro-Mechanics, LG Innotek—despite HBM expertise, lack integrated advanced packaging platforms, risking exclusion from NVIDIA’s next-gen GPU supply chain. U.S. CHIPS Act incentives are fast-tracking domestic entrants like Absolics, distorting market dynamics. If Samsung and Intel fail to achieve cost-competitive yields within 12–24 months, AI chip designers may be locked into TSMC’s ecosystem, cementing its control over the foundational layer of AI hardware infrastructure.
