TSMC’s 3nm Will Come Even Earlier Than Expected: Its CEO Claims 1nm Chips Are Doable
Everything seems to be going smoothly at TSMC, the semiconductor giant that sets the tone and that this week talked about his progress in manufacturing 3nm chips, considered the next “evolutionary step” in a segment that today is dominated by SoCs and memories made with 7 and 5 nm lithographs.
The 3nm manufacturing process has exceeded TSMC’s expectations in such a way that its production will be advanced and will begin mass production in 2022. There is still more, in fact, and this manufacturer has already indicated that 2nm and 1nm chips are already on the horizon.
3nm is close, but 1nm chips are too
Liu Deyin, co-CEO of TSMC, explained at the ISSCC 2021 (International Solid-State Circuits Conference 2021) how everything seems to be going perfectly in his development of 3 nm photolithographic technologies.
That advance is so remarkable that Deyin indicated how the preliminary production of these chips will be advanced in the second half of 2021, and its mass production will arrive in 2022: it will be then when we begin to see the first SoCs that take advantage of this lithography.
The advantages, they explained at TSMC, are clear: these chips will make it possible to increase the density of transistors by 70% compared to 5 nm lithography, and In addition to achieving 11% more performance, they will also reduce consumption by up to 27%.
The first generation of 3nm TSMC chips will use the traditional FinFET process, while Samsung will risk more and use a GAA (Gate All Around) process, theoretically more prepared so that future reductions of the photolithographic scale can be worked on.
At TSMC they have made seemingly remarkable advances in the EUV (Extreme Ultra Violet) machines used to make these chips, and as a result they claim that this process may be used for future 1nm chips.
It is not yet entirely clear when that spectacular technology will arrive, but TSMC is expected to be able to mass-produce 2nm chips in 2023 or 2024 at the latest, which at that rate it would place 1 nm chips in 2026.
