The minimum is 4 nanometers. The current process of the chip is a minimum of 4 nm mass production, and 3 nm can also be manufactured, but the yield is not yet up to commercial mass production. As for the maximum, there is not much limit, and many low-end chips are in the micron scale, that is, 1,000 nanometers.
