TSMC pushes 2 nm manufacturing ahead of schedule, fast-tracks Arizona buildout

[Skye Jacobs]

Something to look forward to: TSMC is moving faster than expected to bring its most advanced chip technology to market. The company confirmed that its N2 process node will enter volume production before the end of 2025, as it accelerates both its domestic rollout in Taiwan and a parallel push to deploy the same technology at its Arizona site.

The N2 node introduces nanosheet-based gate-all-around transistors, replacing the FinFET architecture used since the 16-nanometer generation.

Early yields have been strong, according to company executives, with mass production set to ramp up sharply through 2026. TSMC is also developing a next-step process known as N2P, expected in the second half of 2026, to deliver further efficiency gains.

The 2-nanometer milestone coincides with record financial results for the third quarter. TSMC's revenue rose more than 40% from a year ago to $33.1 billion, powered by demand for AI accelerators and premium smartphone chips.

Advanced process technologies – spanning the N3, N5, and N7 families – made up nearly three-quarters of sales. Company leaders said capital spending will remain aggressive, totaling as much as $42 billion this year, with nearly three-quarters of that directed toward expanding leading-edge manufacturing capacity.

TSMC's Arizona buildout is now central to those investments. The company has already begun producing chips using its N4 process at the first module of Fab 21 near Phoenix and will bring N3 online next. But in an earnings call this week, Chief Executive C.C. Wei said the company will "upgrade our technologies faster to N2 and more advanced processes in Arizona, given the strong AI-related demand from our customers."

That admission marks a major acceleration – N2 production at Fab 21 had originally been expected near the end of the decade.

The twin efforts mark a pivotal moment for the world's largest contract chipmaker as it seeks to meet the surge in global demand for high-performance processors used in AI and advanced computing.

Construction of new modules for N2 and its successor, A16, is expected to begin later this year. When complete, about 30% of TSMC's output from 2 nm-class and more advanced nodes will be produced in the United States.

The company's Arizona site is expected to evolve into a "GigaFab" cluster capable of turning out roughly 100,000 wafers a month, fully integrated with packaging, testing, and local supplier networks.

The shift comes during renewed efforts by US policymakers to secure domestic chip production capacity and lessen dependence on Asian foundries.

Wei underscored that context, describing the Arizona expansion as a step toward creating "an independent, leading-edge semiconductor manufacturing cluster" in the United States. The company is exploring additional land acquisitions around its existing campus to support further expansion beyond its original $165 billion US investment commitment.

No doubt, with TSMC, we can expect their N2 process to be a success. It will be interesting to see if 18A delivers.

Here's something I don't get, everything is made in China, India or Thailand. If TSMC's factories in America produce a load of iPhone chips, don't they now need to be shipped halfway across the world to actually be put into something? Same with GPU's? And almost everything else?

I don't know if these new factories have the packaging capabilities for AMD and Intel's new Chiplet designs but if not, doesn't that mean the chips produced here will also need to be shipped off to actually be packaged properly?

Isn't this a bit "cart before the horse" type thing?

Yes AMD would need to send there dies to Malaysia, Vietnam or China for final packaging. They have done this before with part of the chip coming from Global Foundries in the USA and the main dies coming from Taiwan all being shipped for packaging. Intel packages in the USA, but not much that was the goal with the Ohio plants. Most of there packaging happens in Costa Rica, Malaysia, Vietnam and China. They also now have parts of there chips made in Taiwan with TSMC. If intel gets the Ohio campus completed at some point they can have pretty large scale packaging in the states but it will prob only be for more profitable chips like Xeon or mobile chips. Texas Instruments announced some investment to setup more final assembly work here in the USA to manufacturer final product for industrial usages. This will probably be more of the focus as consumer chips don't have great margins to move to the states without greater automation.
