EUV Lithography and Rare Earth Magnets: An Indispensable Connection
Extreme Ultraviolet (EUV) lithography is the crown jewel of modern semiconductor manufacturing, enabling chips at 7nm and below. At the heart of its ultra precision motion systems lies a material you might not expect: rare earth permanent magnets, primarily neodymium iron boron (NdFeB). A single EUV scanner uses about 10–50 kg of these magnets, and for the foreseeable future, there is no drop in replacement.
