euv is currently as low as 4 nanometers.
euv lithography machine is the world's only high-end lithography machine produced by the Dutch company Asmaire, and the vast majority of its equipment has been purchased by TSMC and Samsung, and Intel has a small number of units. Therefore, the minimum chip nano depends on the ability of TSMC and Samsung. At present, the lowest process chips that have been announced for mass production are 4-nanometer chips, which are the Mediatek Tianguet 9000 manufactured by TSMC and the Qualcomm Snapdragon 8 gen 1 chip manufactured by Samsung.
EUV is currently capable of producing chips as small as 5 nanometers.
EUV extreme ultraviolet lithography machine is a chip production tool, is the core equipment of large-scale integrated circuit production, has a decisive influence on the chip process. Chip wafers smaller than 5 nanometers can only be produced with EUV lithography.
China still has a long way to go, at present, China will achieve 100% autonomous mass production of 28nm chips in 2021, and it is expected to achieve independent mass production of 14nm chips in 2022.
