14nm chips are mainly used in high-end consumer electronics, artificial intelligence devices, application processors, automotive electronics, etc. Chip manufacturing is divided into advanced and mature two processes, with 28nm as the dividing line, the smaller the process, which means the more transistors integrated in a single chip, the more advanced the process. 14nm is an advanced process chip, but compared to the focus of semiconductor competition - 3nm, 5nm, it is still a mature technology. Of all the chips in the Internet of Things era, 14nm chips are becoming the focus of demand.
