1. Now the characteristic size of the chip is a code, as long as the density and performance are improved by 30%-50%, a new generation of processes can emerge, and 0.7nm, 0.5nm, 0.3nm and so on can be produced after 1nm.
Now the technology is more and more developed, chip design will continue to innovate and break through with the development of science and technology, so 1nm chip is not the limit, there will be higher achievements in the future.
