No, because the market now has 28,14nm chip is even number, there are also 7nm, 5nm and other singular chip, which is the national standard size, with the continuous progress of science and technology, chip manufacturing technology is getting higher and higher, and continue to develop to a smaller size, may not be too far in the future, chip size will break through 3 nm technology, Performance will also be improved more.
It's not all singular, it's even, like 10-nanometer processes
