Recently, the semiconductor market has been in turmoil. Huawei is banned in the United States, the global epidemic has led to economic downturn and other factors affecting the development prospects of semiconductors. Previously, there were rumors that TSMC delayed its advanced manufacturing process. Among them, 3nm delayed its trial production for half a year until Q1 next year, but the official denied the news.
TSMC 3nm is the next generation of nodes after 5nm, Official information shows that the density nm 3 process transistors is at the mm of 250 million, while the 5nm process is only 180 million / mmTwoThe performance of 3nm is 7% higher than that of 5nm, and the energy consumption ratio is 15%.
In terms of process, TSMC thinks that the current FinFET process is better in cost and energy efficiency after evaluating various options, so the first 3 nm will still be FinFET transistor technology.
Tsmc has not only reduced production capacity by seven nm、5nm, but also delayed production by three quarters until the Q3 quarter of 2021, leading to a slowdown in demand for advanced processes, nm reports said.
Tsmc today, however, denied rumors that everything was going according to plan, and that the 3 nm process was on schedule for trial production in the Q1 quarter of 2021 and formal production in the second half of 2022.
