RAW MATERIALS🇨🇳 ChinaChokepoint

China mines and processes roughly 80% of the world's tungsten, which is used in semiconductor manufacturing as a tungsten-CVD contact fill material connecting transistors to the metal interconnect layers above. Applied Materials is the leading supplier of tungsten CVD deposition systems; TSMC and other foundries consume tungsten hexafluoride (WF₆) and high-purity tungsten powder in every advanced logic wafer run.
