   ASE Advanced Packaging Quotes Surge 20%+ as WF₆ Supply Shock Threatens Process Materials

   ASE Technology, the world's largest OSAT provider, has reportedly raised advanced packaging quotes by more than 20%, a direct AI-demand-driven price hike that will materially inflate CoWoS and advanced packaging costs for AI accelerator BOMs including H200/B100. Compounding upstream pressure, Kanto Denka Kogyo and Central Glass permanently shuttered their tungsten hexafluoride (WF₆) production lines on July 1, 2026, removing 2,200 tons of annual capacity—approximately 25% of global high-end semiconductor-grade WF₆ supply—due to China's export controls on tungsten raw materials, creating a tightening supply condition for advanced process nodes.

   South Korea Commits $518B HBM & Packaging Capacity Supercycle; Nvidia China Revenue Under Structural Pressure from Huawei

   Samsung Electronics and SK Hynix have jointly committed 800 trillion won (~$518B) to construct two new chip fabrication sites each in South Korea's southwest region, with an additional 81 trillion won earmarked for an advanced chip packaging cluster in the Chungcheong area — representing the largest single sovereign-backed capacity expansion commitment in HBM and advanced packaging history. Concurrently, AP News reports Nvidia's AI chip sales in China are stalling as Huawei captures domestic share, introducing a structural demand-mix risk that could compress Nvidia's addressable volume for H200/B100-class SKUs in the world's second-largest AI market.
