WF6 gas supply squeeze threatens HBM and 3D NAND production

A new supply chain risk emerges: WF6 gas, essential for advanced chip manufacturing (HBM, 3D NAND), faces a squeeze due to Japanese production cuts and Chinese export controls on tungsten powder. This directly impacts NVIDIA's AI accelerator production and could exacerbate GPU shortages and price increases. The timing is critical as AI demand surges.
