High-NA EUV mask materials A team of researchers have presented a new paper on the tradeoffs of photomask absorber materials for high-NA extreme ultraviolet (EUV) lithography. In the paper, researchers concluded that the industry will likely require an alternative mask absorber stack for high-numerical aperture (high-NA) EUV lithography. Fraunhofer, Imec, ASML and Zeiss contributed to the... » read more
