Rumors suggest TSMC will set up a new fab that deploys 2nm and more advances processes in the Central Taiwan Science Park (CTSP) Phase 2, Taichung City, Taiwan. The city mayor Shiow-Yen Lu has confirmed TSMC’s entry into Phase 2, designating all allocated land exclusively for TSMC 2nd Fab in CTSP. According to the local government, the new fab is expected to house “processes advances than 2nm,” expressing the hope that TSMC will bring its latest technology to Taichung City.

The latest news about TSMC’s new plant has emerged. CNA reported that during the regular session of the Taichung City Council on December 12th, the mayor responded to councilors regarding the progress of Taichung’s efforts to attract TSMC’s new plant. Mayor stated that the city government has secured the deal, confirming that TSMC will establish itself in the CTSP Phase 2.

Mayor Lu explained that due to the immense scale of TSMC’s Taichung 2nd Fab, the Ministry of Economic Affairs in Taiwan is assisting as well. While CTSP Phase 1 accommodates numerous companies, almost all the land in Phase 2 is allocated for TSMC’s Taichung 2nd Fab.

In response, TSMC expressed gratitude for the support from the Taichung city government and pledged to continue cooperating with the relevant procedures. Regarding whether Phase 2 of CTSP will adopt technology for 2nm and more advances process, TSMC did not provide further clarification.

TSMC has also responded to earlier reports about Samsung offering discounts so as to be more effective in competing with TSMC for 2nm orders. During a joint interview before the Taiwan Executive Yuan’s Science & Technology Meeting on December 13th, TSMC Chairman Mark Liu stated that TSMC’s customers prioritize technological quality. As for the outlook for the coming year, Liu expressed hope for a very healthy year.

TSMC previously announced in November 2021 that it plans to establish two wafer fabrication plants for the 7nm and 28nm processes in Kaohsiung, a southern city of Taiwan. Construction was set to begin in 2022, with official production expected to commence in 2024. However, following the announcement, there have been changes in the progress of the Kaohsiung plant development.

Firstly, there were reports of adjustments to the 7nm plant by the end of 2022, in response to weakened demand in the smartphone and PC markets. Subsequently, there were also reports of changes to the 28nm plant’s plans.

It wasn’t until TSMC’s Q1 2023 earnings conference that they officially announced the adjustment of the Kaohsiung 28nm plant’s construction plans, focusing on capacity enhancement for more advanced process technologies.

At the time, TSMC didn’t specify the exact advanced process that would be introduced, only emphasizing that the construction of the wafer fab would proceed as planned. This triggered market speculation that TSMC was likely to adopt the advanced 2nm process technology at the Kaohsiung plant, in response to the rapidly growing demand in the artificial intelligence market.

This week, TSMC confirmed that the Kaohsiung plant will adopt the 2nm process technology. TSMC stated that the construction of the wafer fab in Kaohsiung will proceed as usual, but the previous expansion plans will be adjusted to accommodate the production of the 2nm advanced process technology, in response to strong market demand for advanced processes.

As for the specific details and contents of the plant development, they have not been further disclosed at this stage. According to TSMC’s plans, mass production of the 2nm process is expected to begin in 2025, with production bases including the previously announced Hsinchu and Taichung facilities, as well as the newly announced Kaohsiung facility.

In the continued sluggish consumer electronics market and amidst the booming era of artificial intelligence, semiconductor manufacturers are actively targeting high-performance chips and intensifying the competition over the 2nm process node.

TSMC, Samsung, and the newcomer Rapidus are all actively positioning themselves in the 2nm chip race. Let’s take a look at the progress of these three enterprises.

TSMC: Roadmap for 3nm and 2nm Unveiled

TSMC believes that, at the same power level, the 2nm (N2) chip speed can increase by 15% compared to N3E, or reduce power consumption by 30%, with a density 1.15 times that of its predecessor.

TSMC’s current roadmap for the 3nm “family” includes N3, N3E, N3P, N3X, and N3 AE. N3 is the basic version, N3E is an improved version with further cost optimization, N3P offers enhanced performance, planned for production in the second half of 2024, N3X focuses on high-performance computing devices, and aims for mass production in 2025. N3 AE, designed for the automotive sector, boasts greater reliability and is expected to help customers shorten their product time-to-market by 2 to 3 years.

As for 2nm, TSMC foresees the N2 process to enter mass production in 2025. Media reports from June this year indicate that TSMC is fully committed and has already commenced pre-production work for 2nm chips. In July, the TSMC supply chain revealed that the company has informed equipment suppliers to start delivering 2nm-related machines in the third quarter of next year.

Samsung Electronics: 2nm Mass Production by 2025

In June this year, Samsung announced its latest foundry technology innovations and business strategies.

Embracing the AI era, Samsung’s semiconductor foundry plans to leverage GAA advanced process technology to provide robust support for AI applications. To achieve this, Samsung unveiled detailed plans and performance levels for 2nm process mass production. They aim to realize the application of 2nm process in the mobile sector by 2025, expanding to HPC and automotive electronics in 2026 and 2027, respectively.

Samsung states that the 2nm process (SF2) offers a 12% performance improvement and 25% power efficiency increase over the 3nm process (SF3), with a 5% reduction in chip area.

Rapidus: 2nm Chip Making Progress

Established in November 2022, Rapidus gained significant attention as eight major Japanese companies, including Sony Group, Toyota Motor, SoftBank, Kioxia, Denso, NTT, NEC and MUFG jointly announced their investment in the company. Just a month after its founding, Rapidus forged a strategic partnership with IBM to jointly develop 2nm chip manufacturing technology.

According to Rapidus’ plans, 2nm chips are set to begin trial production in 2025, with mass production commencing in 2027.

[Update] Intel: Being Ambitious to Start Mass Production Of Its 20A Process in The First Half of 2024

Intel is making a vigorous stride into the semiconductor foundry market, setting its sights on rivals like TSMC and Samsung in the arena of advanced process technologies. Intel’s ambitious road map includes kick-starting mass production of its 20A process in the first half of 2024, followed by an 18A process rollout in 2H24. TrendForce points out, however, Intel has a number of significant hurdles to overcome:

Intel’s longstanding focus on manufacturing CPUs, GPUs, FPGAs, and associated I/O chipsets leaves it short of the specialized processes mastered by other foundries. Therefore, the potential success of Intel’s acquisition of Tower—a move to broaden its product line and market reach—is a matter of crucial importance.

Beyond financial segregation, the division of Intel’s actual manufacturing capabilities poses a pivotal challenge. It remains to be seen whether Intel can emulate the complete separation models like those of AMD/GlobalFoundries or Samsung LSI/Samsung Foundry, staying true to the foundry principle of not competing with clients. Adding complexity to the mix, Intel faces the potential exodus of orders from a key customer—its own design division.
