The lithography machine used by the Dutch company Asmail.
The 14nm chip mass production is using the duv lithography machine produced by the Dutch Asmail company. 14nm chip mass production should refer to SMIC's foundry chip technology to reach 14nm process, and this company basically uses the lithography machine of Asmer in the Netherlands. Because Shanghai Microelectronics currently has only 90nm lithography machines, the amount is very small and not suitable for manufacturing 14nm chips. Japanese Nikon and Canon lithography machines are also similar, so the medium and high process chips are used by the Dutch Asmer duv lithography machine.
