TSMC will start mass production of 3nm chips in the second half of 2022


Taiwanese chipmaker, TSMC, will commence the mass production of 3nm chips in the second half of 2022. This is the latest report with respect to the development of TSMC’s 3nm manufacturing process. In addition, the monthly production capacity of this process will be 55,000 pieces. According to TSMC’s Chairman, Liu Deyin, the number of employees in the Tainan Science Park will reach about 20,000 when the 3nm chip starts mass production. The current number is 15,000.


In August of this year, Mi Yujie, senior vice president of TSMC, said that the company has plans to continue to provide meaningful node improvements until N3 and below. TSMC expects N3 to have the latest and most advanced node in 2022. Compared with N5, the benefits are similarly small, performance is only improved by 1.1-1.15 times, and power consumption is reduced by 1.25-1.3 times. These gains are relative to N5, not N5P. 

If you compare the performance with the 7nm process, N3 performance improves by 1.25 times – 1.35 times. Also, the power consumption reduces by 1.55 times-1.6 times under the same usage. In these comparisons, all the multiples you see assume an idealized transistor, which does not necessarily match the actual products manufactured by AMD, or Intel.

TSMC N3 will continue to use FinFET fin field-effect transistors instead of transitioning to GAA wraparound structure field-effect transistors. This is different from Samsung, which has already stated that it will use GAA at the 3nm node.

Samsung to mass-produce 3nm chips in 2022: Striving to overtake TSMC

Samsung and TSMC are the only two companies that have the capacity to make chips with the 5nm process. However, Samsung seems to be in the shadow of TSMC but it is putting up a good fight. According to recent reports, Samsung Electronics is struggling to catch up with TSMC. The South Korean manufacturing giant plans to mass-produce 3nm chips in 2022.

Samsung Electronics executive Park Jae-hong said at an event recently that the company has set a goal to mass-produce 3-nanometer chips in 2022. The executive revealed that the company is already developing preliminary design tools with major partners. Presently, it has invested $116 billion in its next-generation chip business. This includes manufacturing chips for external customers.

Samsung Electronics leader, Li Zaiyong, has previously revealed that the company plans to use the latest 3-nanometer gate-all-around (GAA) process technology that is being developed to manufacture cutting-edge chips and provide them to customers around the world.

As we all know, the company has commenced the mass production of 5nm chips and is developing a 4nm process. In the chip foundry business, Samsung Electronics currently ranks second. It is second only to TSMC which holds the top position with a 52% market share as of last year.
