TSMC welcomes EMIB relief as MediaTek pressure eases

TSMC’s public welcome of rival advanced packaging capacity is a tactical concession to CoWoS/EMIB bottlenecks. Technically, this accelerates Chiplet ecosystems away from single-source dependency toward multi-vendor validation, pressuring ASE, Amkor, and Samsung’s OSAT units to fast-track 2.5D/3D integration. On compliance, U.S. CHIPS Act mandates for domestic back-end capacity force customers to diversify georisk—TSMC’s stance mitigates delivery default risks from its Arizona backend shortfall. Strategically, Intel may leverage EMIB’s cost edge to capture mid-tier AI chip orders, while fabless firms like MediaTek gain pricing leverage. Over the next 12–24 months, advanced packaging will shift from 'capacity scarcity premium' to 'standardized interface competition,' with interoperability leadership determining ecosystem control.
