14nm chip is one of the current mainstream chip manufacturing processes, which has a high manufacturing cost, but can achieve higher performance and power efficiency. At the national level, whether it is sufficient depends on the specific application needs and market size.

At present, the semiconductor industry around the world is constantly developing, especially in the fields of artificial intelligence, the Internet of Things, 5G, and so on, and the demand for chips is increasing.
If the domestic market demand is large, and the domestic chip industry can not meet the demand, then you need to import chips.
Based on current technological development and demand, 14nm chips may not be enough at the national level. With the rapid development of artificial intelligence, big data, cloud computing and other fields, the demand for chip performance and processing power is also increasing. 14nm chips are relatively old, and their performance and capabilities may not meet future needs. Therefore, the country may need more advanced chip technology to meet the growing demand for scientific and technological applications.
It is understood that 14nm and 28nm chips can meet most applications, especially automobiles, televisions and other equipment, and the requirements for chip technology are not very high, of which 14nm can be put into the computer. 5nm is mainly used in highly intelligent electronic devices such as mobile phones. For China, 14nm technology has matured, so Hu Weiwu believes that the top priority is to optimize the system, rather than force the development of 5nm.
