Hi Aperture05,There is a lot of misinformation about silicon manufacturing on this thread. The fact of the matter is that it will be very hard for Chinese fabs (or rather fab, singular) to move to anywhere smaller than their current node. The single greatest monopoly in the silicon manufacturing industry is ASML, which currently makes the only competitive EUV lithographic machine in the world. The Dutch government have withheld issuing export licenses to China, which means that there is no way for SMIC to achieve a node shrink beyond a certain limit.
Shanghai Microelectronics have only achieved a 22nm lithographic machine, and very recently too. All other machines are basically made by US companies such as Lam research.
Your new to this thread, I will advise to read all the post from the start, your subject matter had been debated to death, all we have to do is wait for 2022 for the expected domestic EUV to arrive, 2021 for the 28NM SMEE DUV.
