At 5 nm, the company is currently offering products based on the N7 and N7P processes to customers. But as they move toward 5nm, the two Jahons share some design rules.
Compared to the 7nm derived process, the new N5 process will add complete nodes and make extensive use of EUV technology in more than 10 layers to reduce the total steps of the 7nm process. In addition, TSMC will use fifth-generation FinFET technology.
At present, the most powerful chip manufacturing in the world is TSMC, which is already 5nm. Due to the late start of China, the mastery of relevant technologies is far from enough, as of October 2020, the most advanced is 14 nm.
