At present, SMIC is developing seven-nanometer chips, but there is no way to mass production, and there is no commercial output, SMIC has been able to achieve a commercial output of about 15 nanometers, these chips are mainly used in automobiles and so on, so although our domestic cars are affected by the chip, the output has not decreased significantly. I believe in the future. With China's investment in science and technology, five nanometers, seven nanometers is not a problem
