April 18 news, according to foreign media reports, TSMC still uses the fin field effect transistor architecture of the 3nm process, in December 29 last year officially began commercial production, after mass production capacity continues to increase.

For the 3nm process, which has been produced by TSMC for a quarter, some foreign media reported that the current rate of quality products is 63% or lower.

In terms of the quality rate mentioned in foreign media reports, there is still a gap between the current quality rate of TSMC's 3nm process and the earlier 4nm production. Foreign media reported that the quality rate of TSMC's 4nm process is currently expected to be about 80 per cent.

Although the quality rate of 3nm process of TSMC is expected to be different from that of 4nm at present, it will continue to improve with the extension of mass production time, and it is expected to reach or even exceed the level of 4nm process in the future.

At present, two foundry manufacturers around the world have mass-produced 3nm process, and the other is Samsung Electronics. Samsung Electronics' 3nm process was mass produced on June 30 last year, nearly half a year earlier than TSMC, and the first wafers manufactured by Samsung Electronics were also shipped on July 25 last year.

However, foreign media did not mention the current quality rate of Samsung Electronics 3nm process in their reports, but they said that the quality rate of Samsung Electronics 4nm process has improved significantly, reaching at least 70%, which is close to that of TSMC's 4nm process.
