As the world’s largest and most advanced wafer foundry,
TSMC plans to invest 100 billion US dollars in the next three years
TSMC plans to invest 100 billion US dollars in the next three years , of which advanced technology spends the most money. The 2nm process is also an unprecedented new process. TSMC said last year that the 2nm process has made significant progress and the progress is better than expected.
In fact, TSMC’s 2nm process is not as exaggerated as it was advertised. It was only at the technological exploration stage and found a feasible technological path.
Now the 2nm process has entered the research and development stage,
and the focus has shifted to the direction of test carrier design, mask production, and silicon trial production.
According to TSMC, at the 2nm process node, they will also abandon the FinFET transistor structure and switch to the GAA surround gate structure . Previously, Samsung was more aggressive and would abandon GAA transistors at the 3nm node . However, the two GAA transistor structures are also It won’t be the same, and which one is better is still inconclusive.
At the 2nm node, the lithography process is more important.
EUV lithography is indispensable, but there are still many problems with the previous EUV process. TSMC’s 2nm node will also focus on improving the EUV process to improve the quality and efficiency of lithography.
As for the time for mass production, TSMC’s 2nm plant is still in its infancy. Earlier, it was reported that the 2nm process will be trial-produced in 2023 and mass production will be in 2024 .V#duzline #2nm #TSMC
