Domestic chips can be as small as 7 nanometers.
The domestic chip manufacturing industry leader to see SMIC, SMIC's manufacturing capacity can reach the highest 7 nanometer process, but this 7 nanometer process is not yet mass production, because the yield should be relatively low, the cost is very high. Smic can mass produce the highest actual chip manufacturing process of 14 nanometers, this process of chips can already meet the low-end chips.
