TSMC To Build 5nm Fab In Arizona, Set To Come Online In 2024by Ryan Smith on May 15, 2020 10:00 AM EST

In a big shift to their manufacturing operations – and a big political win domestically – TSMC has announced that the company will be building a new, high-end fab in Arizona. The facility, set to come online in 2024, will utilize TSMC’s soon-to-be-deployed 5nm process, with the ability to handle 20,000 wafers a month. And with a final price tag on the facility expected to be $12 billion, this would make it one of the most expensive fabs ever built in the United States.
Operating over a dozen fabs across the globe, TSMC is responsible for a significant share of global logic chip production, particularly with leading-edge and near-leading-edge processes. The company has become perhaps the biggest winner amidst the gradual winnowing of fabs over the past two decades, as manufacturer after manufacturer has dropped out, consolidating orders among the remaining fabs. And with GlobalFoundries dropping out of the race for cutting-edge manufacturing nodes, TSMC is one of only three companies globally that's developing leading-edge process nodes – and one of the only two that’s a pure-play foundry.
This success has become both a boon and a liability for TSMC. Along with Korean rival Samsung, the two companies have seen massive growth in revenues and profits as they have become the last fabs standing. As a result, TSMC serves customers both locally and globally, particularly the United States and China, the two of which are not enjoying the best of relations right now. This leaves TSMC trapped in the middle of matters – both figuratively and literally – as China needs TSMC to produce leading-edge chips, and the United States is now increasingly reliant on TSMC as well following GlobalFoundries’ retreat.
As a result, the Taiwan Semiconductor Manufacturing Company is going to do something it’s never done before, building a near-leading-edge fab in the US, outside of its home base of Taiwan. The new facility, set to be constructed in Arizona, will use the company’s 5nm process, which is currently TSMC’s most advanced manufacturing process. And while this will no longer be the case by the time it comes online in 2024, when 3nm processes are likely to be available, it would still make the Arizona facility among the most advanced fabs in the world, and by far the most advanced contract fab in the United States.
The Arizona facility would be joining TSMC’s other US fab, which is located in Camas, Washington. It, like TSMC’s other non-Taiwanese-fabs, is based around older technologies, with the Camas fab in particular focusing on building flash products using relatively large process nodes (350nm to 160nm). As a result, the Arizona fab represents a significant shift for TSMC; it’s not the first US fab for the company, but it’s the first time TSMC has built such an advanced fab in another nation.
All told, the Arizona fab is set to be a medium-sized facility – a “megafab” in TSMC parlance – despite its use of an advanced manufacturing node. The 20,000 wafers per month throughput of the fab is well below TSMC’s largest “gigafabs” in Taiwan, which can move more than 100,000 wafers per month. As a result while the fab will add to TSMC’s 5nm capacity, it won’t become a massive part of that capacity. Though with an expected price tag of $12 billion, it will still be a very expensive facility to build.
According to TSMC, the primary impetus for building the fab – and especially to build it in the United States instead of Taiwan – is specifically to have high-end production capacity within the United States. With GlobalFoundries dropping out of the race for leading-edge nodes, the US government and other sensitive fabless chip designers are in want of another leading-edge facility within the US to build their chips. Given their location, TSMC’s Taiwanese fabs are seen as security risk, and the US would prefer to be self-reliant rather than relying on a foreign partner – a concern that’s been magnified by the current coronavirus pandemic and the supply chain issues that has created.
The end result is that while the fab is not explicitly reserved for military and other sensitive chips, it’s hard to imagine a scenario where the big commodity chip manufacturers such as AMD and Qualcomm don’t continue to use TSMC’s larger and more efficient fabs in Taiwan. In other words, while the Zen processor you’re playing World of Tanks on isn’t likely to come from Arizona, the chip that goes into an actual tank just might. Unaspiringly then, the planned Arizona fab comes with a lot of interest and support from both Arizona and the US Government, for both strategic and business reasons.
Interestingly, while the desire for more domestic fabs within the US has been well known, the US’s two major domestic fabs find themselves on the outside looking in with this deal. Intel has long tried to lure customers to its own contract manufacturing business, including making pitches to the US government, with little luck. Meanwhile GlobalFoundries is currently the US government’s preferred fab for military hardware – inheriting those fabs and the resulting business from IBM – but whom faces the prospect of slowly losing business as government customers switch to newer manufacturing processes. So in some respects it’s a bit surprising to see outsider TSMC land such a deal, though there are sizable political concerns involved as well.
At any rate, TSMC’s Arizona fab is expected to break ground in 2021, with completion scheduled for 2024. At which point it is anticipated to employ over 1600 workers as TSMC becomes the United States’ second leading-edge foundry provider.

melgross - Tuesday, May 19, 2020 - linkApple didnt “reel them in”. You apparently don't know the history of that. It’s public. They were making sapphire Windows for Apple’s cameras and Touch ID button. They were also the world’s largest maker of sapphire, and the ovens, which they also sold to others, Apple approached them about making sapphire for their phone screens. They said they designed bigger ovens, and that they could do it when needed. Apple gave them over $400 million to develop it, and bought a factory, paid to refurbish it, and paid to run it themselves.
But their ovens never worked properly, and the bullies came out clouded, cracked, and with other problems. It turned out that the company knew they were having these problems, but didn't tell Apple until the last minute. Meanwhile company executives sold large amounts of stock, which had risen because of the Apple deal.
This fiasco cost Apple an estimated $600 million. They ended up buying many of the non working ovens, and the rest were sold by what remained of this company, which as I remember, is still around.
darkvader75 - Monday, May 18, 2020 - linkA last-gen fab for 2024 after 5 billion dollars. The current-gen will be 2NM at that point not 5. So this will be an out of date FAB the day it is made.
nandnandnand - Monday, May 18, 2020 - link1. It's good enough and pretty close to the end of node shrinkage.
2. 32nm, 45nm, 90nm, etc. are still in use.
3. They can upgrade it later if they feel the need to.
FunBunny2 - Wednesday, May 20, 2020 - link"The current-gen will be 2NM at that point not 5. So this will be an out of date FAB the day it is made."
Enquiring minds want to know, what is the breakdown of a fab's (initial) cost:
1 - land
2 - the building
3 - utility installation
4 - connections to those utilities
5 - the machines
so, one might conclude that some/most/all of the machines have to be swapped out. and, perhaps, more water and electricity.
adin - Tuesday, May 19, 2020 - linkTSMC will invest $1,3B each year but another will invest rest $200M . DoD or Intel ?
melgross - Tuesday, May 19, 2020 - linkApple?
peevee - Tuesday, May 19, 2020 - linkFINALLY!
I hope Apple will produce their CPUs and iPhones here too.
China must go.
