The current Kirin 980, Kirin 810, Apple A12, A13, Snapdragon 855 all use 7nm technology. With the development of emerging technologies such as 5G, there is an opportunity to enter the era of 5nm and below in 2020.
After the introduction of EUV technology in wafer foundry, the established process node can greatly increase the transistor density, and the importance of EUV has become increasingly prominent in the later period of Moore's Law.
The more structures a future chipmaker can cram onto a chip, the faster and more powerful it will be. So the goal of the relevant enterprises is to try to reduce the size of the structure. After the introduction of EUV technology, it is possible to make smaller, faster and more powerful chips.
