Earlier this month, we saw that TSMC was getting its CoWoS interposer and 5nm production lines at full capacity. Yesterday, we found out that AMD and Nvidia bought up all of their excess capacity for next-generation GPU and CPU development. They have also been making advancements in 3nm process development, but have not been able to put much work in because many of the tools necessary are currently unavailable or hard to find due to the COVID-19 pandemic. 3nm is already a lot of work as it is, but in a recent shareholders meeting, DigiTimes was able to figure out that TSMC is already planning to start the development of the 2nm Lithographic process.

The details on this process are so bleak that all we know is that they are starting on the development process of 2nm, and that's all we could dig up at the moment. As more news surfaces, we will continue to update you. One thing is for sure with 2nm silicon, it will be significantly faster and much more efficient than what we have now. At the forefront of their current advancement and development are the 5nm chips which are created using EUV lithography similar to what Samsung is doing. DigiTimes report that TSMC expects 10% of the revenue from this year will be from 5nm chips.
