Source: TSMC's US division president said during a webinar that production yields in Arizona are 4 percentage points higher than at similar facilities in Taiwan
TSMC’s Arizona ramp had been defined by execution concerns: a skilled-worker shortfall pushed its 4nm production target into 2025, while a later labor agreement addressed disputes around foreign workers. By September, reporting said the site had reached yield parity with established Taiwan plants.
The reported four-point lead turns that progression from a construction-and-staffing story into evidence that Arizona can perform competitively at the production level. That matters because TSMC is also planning to use its US commitment to expand Arizona capacity.
First-order effects
TSMC can point to Arizona yield performance as validation of its US manufacturing ramp, strengthening the operational case for bringing more output online there.
US customers seeking advanced chips gain a more credible domestic production option as the Arizona site moves beyond the earlier delay tied to skilled-worker shortages.
Second-order effects
The result raises the bar for future overseas fabs: TSMC must show that geographic expansion can preserve yields even as it has forecast margin dilution during overseas ramp-ups.
Arizona expansion plans gain support, but the reported yield advantage does not by itself remove the cost and staffing pressures that previously complicated the site’s build-out.
Third-order effects
If repeatable, competitive yields in Arizona would reduce the industry’s reliance on a single manufacturing geography for leading-edge output, though capacity scale and economics remain separate constraints.
The story is an early test of whether geographically diversified chip production can shift from resilience policy to an operationally viable second source.
The trend: Leading-edge chip manufacturing is moving toward qualified multi-region capacity, with yield performance becoming the decisive proof point for diversification.
Thanks to the Democrat's #CHIPSAct, TSMC's new Arizona plant is already outperforming expectations - a massive win for U.S. innovation! This is how we create good-paying jobs, boost our economy, and maintain American leadership in advanced manufacturing and technology.
Pretty clear that TSMC's execs are full of shit. They said that the U.S. could never be a good place for production, then said U.S. workers couldn't do a good job, then after they got subsidies all of a sudden... [image]
Worth marveling at the fact that the CHIPS and Science Act was only signed into law in August 2022. Two years later, the premier chips manufacturer in the world, TSMC, has a plant in production in Arizona. Huge, huge win. [image]
The critics would have had you believe that DEI killed CHIPS, ending American hegemony. Instead, not only are we producing chips better than Taiwan, we are also further increasing American cultural exports, by training TSMC in the ways of DEI.
Assuming this continues to be true at larger production scale it's an unbelievable achievement and harbinger of very good things to come for our nations future as an industrial and manufacturing juggernaut 🇺🇸💪🏼
This is surprising to everyone who forgot that we built plenty of fabs in the US in the 1980s and 1990s. My hometown had a few nearby. Somehow all this history faded and everyone thinks we can't do this work in the US at all.
TSMC's Arizona plant is nuclear-powered, from 3 giant reactors in the middle of the desert using Phoenix's treated waste water. Meanwhile Taiwan is about to crash its electricity grid in an insane crusade to close all their nuclear plants and run on imported fossil fuels.
@ChorzempaMartin Lets be clear, this is NOT “US manufacturing” by any stretch. Let's also be clear that this is a tiny portion of TSMC's advanced node capacity on Taiwan and will be for the foreseeable future, think 10 years or more. In addition, let's be clear that the troubles …
Amazing win for US manufacturing (run by Taiwanese) after a lot of bad press and doubt that U.S. could make advanced chips. If yields are better than TW not clear made in USA chips have to be more expensive...
We are finally doing industrial policy and finally doing industrial policy well for the first time in decades and the whole Biden team deserves a ton of credit for that. Lots of people thought this was impossible a few years ago.
This is insane if it's actually true Could completely change the power dynamics between China and the US, and how much of a threat them taking over Taiwan is... [image]
“The share of chips manufactured at TSMC's facility in Phoenix that are usable is about 4 percentage points higher than comparable facilities in Taiwan...”
