is not
Smic basically uses the duv lithography machine of the Netherlands Asmer Company, and domestic lithography machines may also have such as Shanghai Micro Electronics, but the 90nm low-end lithography machine is difficult to achieve the 14nm process. If you want to reach the mass production of 14nm chips may need to use 28nm mid-end lithography machine, the current mass production of mid-end lithography machine is the Netherlands Asmer, Japan Nikon and Canon I am afraid the output is very low. Therefore, the high probability that SMIC 14nm is a Dutch lithography machine is not a domestic lithography machine.
