According to the current technical level and market demand, China's self-produced 14nm chips may not be enough to meet China's self-use needs. With the continuous development of technology, the demand for chips is increasing, especially in the fields of artificial intelligence, cloud computing and the Internet of Things. Therefore, China needs to further enhance the chip manufacturing capacity, increase research and development investment, and improve the level of manufacturing technology to meet the growing chip demand in China. At the same time, it is also necessary to strengthen international cooperation, introduce advanced technology and equipment, improve independent innovation capabilities, and achieve sustainable development of the chip industry.
