I've always thought that TSMC's dominance in fab processes are a strategic asset in the defense of Taiwan against potential PRC encroachment. I would assume that as long as a large part of the global tech industry relies on TSMC, countries such as the USA would have a strong incentive to potentially protect Taiwan against threats. Does anyone have insight into the geopolitical impacts of Taiwan - USA relations in regards to TSMC fabs on US soil? Would Taiwan view this a strengthening of relations between the two, as I would assume this provides the USA with some "domestic" 5nm fab capacity, or is there some risk in that once this fab comes online the USA may see Taiwan as less critical? Anyone know some good sources discussing the above?

It seems that the arrangement is a win-win for both sides. By the time the 5nm fab is in operation in 2024, it will be old tech for TSMC, since they are planning to have 3nm in high-volume production and 2nm already in risk production. The fab may very well still be the most advanced in the US, depending on whether Intel gets their 5nm process ready as planned in 2023.

Your guess is pretty on the point. TSMC has been jokingly hailed as "The protector of the country" by the Taiwanese media. The chips have military significance for the USA, as it has been trying to avoid China made electronics in all (or most?) equipments.
YetAnotherNick 6y ago
While TMSC is no doubt ahead of competition, it is just by margin of 1-2 generations at max, which accounts for max 2-3 years for friendly country like Korea to catch up. So if some Taiwan politics comes into play, we will just lose the progress for some years of semiconductor fab tech, not a small thing but it is not that the chips couldn't be built if not for Taiwan. We would just lose something like 10-20% of performance in the chip.

  I would argue the opposite, that it is a huge deal for defense. Imagine if the situation is missile defense, both the missile and the defense systems are computerized and not only the milliseconds but also the microseconds are the difference between a hit and a stopped missile. Whoever had the newest fab node would have a notable advantage in being able to push their system harder. It could be better ML in missile to lock on and dodge, vs the defense system predicting paths as fast as possible with as low latency as possible to defend a ship or similar asset. Its asymmetric in the example of course, but both sides would be doing both shooting and defending.
  - FrojoS 6y ago
    Your scenario is not founded in reality. Few problems that involve computers are limited by or can primarily be solved by computer technology. In your example, one of the main challenges is that every missile defense system can be overwhelmed by shear number of attack missiles. Have a look at what type of microchips are used in “cutting edge” military equipment like fighter jets. They are often decade olds. More speed is simply not important enough.
    - xupybd 6y ago
      Not only that but smaller cores are less radiation resistant. Meaning more likely to get interference from natural radiation sources. So less reliable.
    - Buraksr 6y ago
      I think what you say is correct, its so much easier to fire a missile than it is to stop one. Honestly, reliability and cost are bigger drivers than raw performance. The scenario is a bit bad I can admit, and did admit. But if we were in desperate times, I think the limits would matter and fab tech would be an important strategic asset for what it enables. The nature of it is that its easier to attack, but we hopefully have something to defend. Intrinsically larger process nodes are better for analog and have uses even as new fabs come along. In 7nm your analog signals are not treated very nicely, but these are important for sensors. Also power electronics are not really on the newest nodes either. The microchips are old because they get the job done and I don’t think we feel so threatened to push the limits.

It's amazing how we're making lofty long-term projections, including defense strategy, Taiwan's sovreignty and global state of affairs from something that wasn't true just 5 years ago. TSMC has lead in development right now. Intel isn't dead and it can catch up, I am hoping just as TSMC caught upto Intel. There is no guarantee that TSMC might get stuck at a node in future for Intel to catch up. Neither is there any guarantee for Intel to find a technology breakthrough and make progress in leaps and bounds. Remember, there was no tick-tock cycle before Intel invented the 2 year cadence back in ~2008. It was a business strategy to push alternate cycles of architecture changes and process node changes. It was conceived and invented by Intel. The point is that the cadence the entire industry judges itself was coined by the leader of the industry at the time. Now, the leader's podium position isn't at the top.
- comboy 6y ago
  1st place is only part of the equation. They are a very important player, have been for some time and many big companies depend on them and will still depend on them even if Intel gets its stuff together. But global dynamics seem very interesting currently. Big tech influence on political issues and wars have been big for some time but is becoming very visible now. Taiwan would be a very different country without TSMC. Heavily optimized for cost and speed and less on reliability supply chains and mining industries. It seems hopeful to me that future wars will mostly be cyber and economical, it could mean less people suffering but it's not granted.

  >Remember, there was no tick-tock cycle before Intel invented the 2 year cadence back in ~2008. There was no Tick Tock then, but there was Moore's law. Intel unable to improve their node and manufacturing has nothing to do with Tick Tock cycles. >There is no guarantee that TSMC might get stuck at a node in future for Intel to catch up. They did. 3nm is no longer using GAAFET. And they have a plan B with 3nm using FinFET. We judge a company by its past, and present experience. TSMC has always been an open, transparent and conservative company. Much like ARM, they are not there to take the spotlight. They were suppose to be in the background helping companies, it was only in recent 5 years Main Stream Media decided to hype it. Mostly because of Apple.

Of course TSMC makes Taiwan important for the US, so in that sense it protects Taiwan. But it is also a big game of chicken. If the mainland decided to invade (and they are not in a position to do so) the US would not start WWIII by going into a direct war against them.
- mamon 6y ago
  That's not how it works. First: US make a lot of promises to a lot of countries. If they are not willing to go to war over Taiwan, that makes most of those promises (like NATO pact) basically worthless. So US has to defend Taiwan. Second: Military confrontation between US and Chinese forces does not mean WWIII - they won't start shooting nukes, it will be more conventional war. We had such examples during previous Cold War: Korea, Vietnam, Afghanistan.
  - mytailorisrich 6y ago
    > If they are not willing to go to war over Taiwan They are not willing to do to war over Taiwan. The opposite would be insane. Equally China is not willing (and able) either. This is a balance of threats with both sides knowing where to stop. The US are obviously not stupid and they never committed to intervene against China. They have just committed to 'help' and make sure that Taiwan can defend itself, which is very different. > Military confrontation between US and Chinese forces does not mean WWIII It does when the US directly attack the Chinese over Chinese territory. I.e. the US would be declaring war on China. I would not let anyone who does not see the insanity of that prospect have a job in government.
  - forty 6y ago
    I'm not even sure it would be a conventional war. More a digital and commercial war I would bet (which is already happening I guess). Something like the US and their allies stopping to purchase anything from China, if that's even possible. Look at what happened in Ukraine, Russia got a few sanctions from EU, but as far as I know, they are still trading with them, purchasing their gaz.

andy_ppp 6y ago
My guess would be there is a plan for the US to bomb the TSMC factories in the event of China winning an extremely costly war against Taiwan. I’m not sure the US would actually come to Taiwan’s aid. I mean surely Taiwan has enough arms to destroy a very expensive chunk of Beijing and Shanghai in response to any invasion? Terrifying stuff...
- pm90 6y ago
  It’s almost certain that the US would be involved if the PRC chose to invade Taiwan. Losing Taiwan would be a geopolitical catastrophe: protecting Taiwan from an invasion with the Pacific fleet would be critical in preserving the Taiwanese Armed forces and thus preventing more American lives from being spent in the war. Seems pretty far fetched considering today’s economic and political conditions though.

        Taiwan say no is sure. But china is getting not much bad news. If he can transform into a totalitarian control regime but still attract foreign money and trade ... plus a bit sanction. May be they can do Taiwan as well. It would break the balance and has a platform to launch to pacific. It showed America is just paper tiger (and Asian countries would “know”). China may try. As one of the top guys said we can lost 1 billion chinese still the second largest country on the world (in terms of population). After Korean War do not underestimate the craziness of unification (see how south be defeated and china later involved). No one want this war. But the incentives of china is still here.

1. This is a very small Fab, comparatively speaking, and it is likely for specific use. ( I am guessing military ) 2. 5nm in 2024 is at least 4 years / 2 Node behind leading edge. Given the complexity with the project I actually expect HVM happens in 2025. They will of course produce something in 2024 just to make headlines, but HVM always start later. ( The public wouldn't know or care anyway ) 3. This means TSMC in Taiwan is still as important it was, and arguably more so in 2024. From Geopolitics prospective this Fab doesn't change a thing.
dirtyid 6y ago
Every major bloc now has significant investments in reshoring indigenous semi capabilities, policy discussions dance around the fact that diversifying would be Taiwan's doom. There is limited timeline where TSMC will serve as security shield for the island. I see a lot of discussion here that US would glass TSMC fabs if China ever attempted takeover, when realistically China would be the ones to disrupt TSMC proactively and prematurely if PRC indigenous semi industry reaches useful levels. Catching up to EUV is much harder than undermining it. Chinese military modernization = the first island chain strategy is dead. Taiwan never got security guarantee precisely because other strategy to contain China existed (malacca / sloc chokepoint), TSMC dominance is an aberration that no one apart from Taiwan is interested in. Hence I wonder how smooth the Arizona plant will go, possibly foxconn Wisconsin redux, but more pressing.
karmasimida 6y ago
In a full scale war with China, I don't think TSMC's fab can be preserved. China can destroy it without landing on the island, easily. Taiwan is too close to China, that is a reality. Plus, modern chipmaking is an incredible sophisticated business, for example, you need huge amount of electricity and raw materials imported overseas to sustain the fab. When the war breaks, all of that would end. Their effort should be spent on to prevent the war from happening in the first place, that is the only way to 'win' the war.
- tylermauthe 6y ago
  China relies on the fabs in Taiwan just as much as everyone else though. I agree that war should be avoided and "the only way to win is not to play"! However, I think we should also be considering globally how we can act more like Holons [1] for greater resilience from all types of threats to global interdependence. We want loosely coupled systems, we should want loosely coupled government too! [1] https://en.m.wikipedia.org/wiki/Holon_(philosophy) https://en.m.wikipedia.org/wiki/Holon_(philosophy)
- r00fus 6y ago
  Why would China destroy it when they can simply occupy Taiwan without much recourse? I would bet in all their war-games, very few strats have the "TSMC destroyed" scenario checked.
  - viro 6y ago
    > without much recourse? I think you underestimate how violently the US will respond to something like that. It honestly would the greatest existential threat to the US since WW2. Chips are a decent amount more important(at the moment) than oil and look at the crazy shit the US did for that.
    - perl4ever 6y ago
      When people say or imply that the US engages in "war for oil", it's virtually always (in my observation) left ambiguous whether the claim is that the US pursues genuine national interest, or that the foreign policy is subverted by some unspecified special interest not aligned with the US as a whole, such as private oil companies. What are you really saying when you say the US did "crazy shit" [for oil]?
csomar 6y ago
At least, for now, I don't think the US will let Taiwan be eaten by China. The US did protect (and to some extent create) Taiwan long before Taiwan had any value. Taiwan being invaded by China is a signal of the end of US hegemony around the world.
- adventured 6y ago
  > Taiwan being invaded by China is a signal of the end of US hegemony around the world. It'll only loudly signal an end to US hegemony in Asia (which has already happened de facto). That is inevitable regardless of a Taiwan invasion and everyone knows it at this point. China has gained immense positioning during the pandemic while all other major nations have lost. There was never a scenario where the US could retain its former dominance in Asia as China arrived at being a full-fledged superpower (they'll be there militarily this decade). US hegemony, to the extent it exists, will remain intact elsewhere for decades after it lost that status in Asia. US hegemony isn't based on signals and perception, it's based on military force projection and whether there are equal counters to that in a given region. China is very close to powerful enough to counter the US military in the Asia region (not just near its borders) and that determines the hegemony regardless of whether China goes into Taiwan anytime soon. Anyone thinking the US still retains hegemony in Asia is most likely fooling themselves at this point.

    George Friedman and Peter Zeihan say that it is not clear that China would win a war even just against Japan. Both countries rely on imported oil. The most likely cause of a war between them is an oil shortage, giving nations an incentive to use their navies to capture oil tankers. The use of navies to capture cargoes of national importance was common for centuries till end of WWII. It ceased after WWII because of US naval dominance combined with the use of free trade as a part of US strategy in the cold war, but of course the cold war is over; so the US, which has been and remains the power least reliant on international trade, could choose not to spill the blood of US sailors to keep the sea lanes open to all. Japan knows this and has been building a navy that can operate outside the South China sea and in the Indian ocean, so that it can escort oil tankers from the Persian Gulf to Japan. China's navy in contrast cannot operate outside the South China sea, he says. Friedman says that aircraft carriers benefit a country only if it has admirals that know how to use them and points out that Japan's admirals have been trained by admirals trained by admirals that actually used aircraft carriers in a major war. The main purpose of the People's Liberation Army is to put down a rebellion by Chinese citizens. The primary goal and concern of the rulers of China beyond their Party's remaining in power is to prevent the country from splitting apart. For most of the 2500-year history of China, it has been divided into multiple polities, and outside powers have played the pieces off against each other. The US just lost a war against the Taliban, a war it spent many trillions of dollars on, so I doubt the US military worries about whether a loss in a future conflict would signal an end of US hegemony.
