Memory tightness deepens: SK Hynix commits $38bn to new fabs as shortages ripple downstream

Watchlist match: HBM / memory supply

SK Hynix said it will invest $38 billion in new memory-chip plants as AI demand keeps pushing prices up. The squeeze is visible downstream: reporting this week described roughly $1 billion of iPhone 18 Pro chips sitting on shelves awaiting packaging because of DRAM shortages, while Samsung unveiled three next-generation memory technologies for AI data centers — zHBM among them.

China’s homegrown chipmaking-tool push moves from roadmap to production

Watchlist match: US–China export controls

Reuters reported that China has begun producing home-grown immersion DUV lithography machines, and an examination of Beijing’s tool roadmaps put early output at around five machines a year, with an EUV prototype still far from producing chips. Memory maker CXMT — targeting 30% of the DRAM market by 2030 with a sixth mega-fab — remains bottlenecked by access to advanced chipmaking tools, the exact constraint export controls are designed to hold.
