According to the progress of chip technology, after 10nm it will be 7nm, then 5nm, then 3nm, and then 2nm. Why are there such numbers? This is based on Moore's Law. Every time the density of transistors increases, the new process is about 0.7 times the old process. And what proce

has such numbers? This is based on Moore's Law. Every time the density of transistors increases, the new process is about 0.7 times the old process.

And what process will it take when it comes to 2nm? Recently, TSMC has given the answer, which is 1.8nm, also known as 18 angstroms. Starting from 1.8nm, it has officially entered the angstrom era and will no longer use nm as the unit.

According to media reports, TSMC is currently selecting a site for the 18 angstrom process. TSMC's 2nm process Fab 20 wafer fab has currently selected Baoshan, Hsinchu, as the location for the factory.

And the 18 angstrom technology may be settled in Taichung. Now the golf course next to Zhongke Fab 15 factory has been taken into consideration.

In fact, mass production of 18 angstroms may not be until 2026~2027. Currently, TSMC’s real process is still at 5nm.

According to the process roadmap announced by TSMC some time ago, TSMC's 3nm will be mass-produced in 2022, but delivery to customers may not be until early 2023, which is 3-4 months later than expected.

TSMC’s 2nm will not be mass-produced until at least 2025. According to the 2-year generation process, 18 angstrom will not be available until at least 2027.

So why is TSMC so anxious now? The reason is that competition is getting increasingly fierce.

Samsung is the first, and it may lead TSMC in 3nm. Samsung plans to deliver 3nm chips next year. More importantly, Samsung’s 3nm uses GAAFET transistor technology, while TSMC still uses the old FinFET technology, so Samsung has Advantageous.

Next is Intel, which is also developing its foundry business. Maybe it wants to regain its former glory in foundry. TSMC has also launched an IDM2.0 revitalization plan.

Therefore, TSMC is also under great pressure and has to prepare in advance. 3nm is postponed. We don’t know when 2nm will be mass-produced. Let’s throw out 18 angstroms first. As for when mass-produced, there is no rush, just step by step Let me tell you that TSMC is still working hard to move forward.
