In context: Tensions between China and other countries, especially the US, grew earlier this year when the communist government laid claim to the self-governed state. Analysts have many theories about what would happen to the TSMC's factories if China annexed Taiwan. Most agree it would be a bleak outlook for the electronics industry.

Semiconductor analyst Claus Assholm notes that if China invaded Taiwan, one of its goals could be to destroy TSMC's sophisticated chipmaking factories.

As the world's largest contract chip manufacturer, TSMC's destruction would severely disrupt global supply chains. However, Assholm's analysis contradicts much of the strategic thinking surrounding China's possible invasion of Taiwan and how it would impact TSMC.

Conventional thinking is that if China successfully invades Taiwan, it will attempt to control TSMC operations. Of course, this would be very challenging considering the increased international sanctions it would face. The island nation's global supply chain partners are aware of the damage this would cause and are trying to devise alternative solutions.

Bloomberg notes one alternative is to disable its plants remotely. According to people familiar with the matter, TSMC has this capability. More drastically, some US politicians advocate either the US or Taiwan destroy the factories so they don't fall into China's hands. Taiwan has come out strongly against this, especially at the hands of the US.

However, Assholm ponders the worst-case scenario: "What if China is not deterred by potentially mined TSMC factories and ASML kill switches? What if the reunification plan is based on eradicating the TSMC factories and the Semiconductor supply chain in Taiwan and beyond?"

China might be tempted into such an act by visions of dominating the world's supply chain. Assholm notes that Taiwan and South Korea own 22 and 28 percent of the global semiconductor market, respectively.

Meanwhile, China has a 12% stake, making it the third largest player. If both countries are removed from the equation, which could happen if there were a conflict in the region or between Taiwan and South Korea, China would possess about one-third of global semiconductor capacity, making it the leading global electronics supplier.

Assholm speculates that if this were to happen, the US would be forced to buy from China, setting back domestic electronic sectors by 15 to 20 years or until the US built enough chip factories to become self-sufficient, which will be no easy task.

Boston Consulting Group points out that as of 2021, the US only accounted for about 12 percent of global semiconductor manufacturing capacity, down from 37 percent in 1990. While the CHIPS and Science Act, passed in 2022, allocates $52.7 billion over five years to encourage semiconductor development and research in the US, its impact will take decades to materialize.

The do not have to invade anything to kill cpu/gpu or silicon based production of electronics. The control in-country 85+% of all cpu / gpu grade silicon production and refinement for the entire earth. all they need to do is stop selling the silicon as there are no other sources on earth that match the purity at the source and no other sources on earth that can produce even 10% of the worlds pure silicon needs.

China controls/owns 85+% of all CPU GRADE silicon production, not only as a purer source straight out of the ground, but also on a cost/tonne in refinement and production. If china embargos that refined silicon most all silicon based production on earth ends in 60 days.

This simply isn't true. The vast majority of China's silicon wafer production isn't of the grade needed for electronics semiconductors, it's photovoltaic grade. True, they could produce that grade if/when push comes to shove, but semiconductor ("cpu/gpu") silicon purity is orders of magnitude greater than photovoltaic. Photovoltaic=99.9999% (six nines), semiconductor wafers=99.9999999 (nine nines, alternatively characterized as '9N') to 99.999999999% (eleven nines, '11N').

The US has a robust silicon mining, purification, and wafer industry, as do South Korea and Japan. There are mines in Alabama and South (or is it North) Carolina that produce top notch quartz for silicon production. True, South Korea and Japan are in close proximity to China, but China doesn't lay any claim to either of the countries, unlike Taiwan.
 
Nan - silicon supply chain is dependent on China only because we don't want to compete with the cheap labor costs for mining and manufacturing. If that supply is cut off, it wouldn't take long to replace because the tech and training needed is minor. TSMC's capabilities on the other hand are much harder to replace and why it is considered a strategic asset. Honestly would be cheaper to buy a large chunk of land - say from Brazil - and move Taiwan there than deal the fallout of an invasion.

To be clear though, none of that would mitigate the semiconductor 'starvation' that would occur if TSMC's production were destroyed, or simply repurposed by China for their own purposes.

Have to correct myself - Japan/South Korea have silicon purifying/refining industries and wafer production, but they don't have high quality silicon mines. That said, there are plenty of other sources - 'non conflict' so to speak - of high enough grade silicon that wafer production wouldn't be deeply affected. But the same caveat again applies, as TSMC in Taiwan produces the largest amount of finished semiconductor products in the world.
 
Here's what will happen if China invades and are successful in taking control of the country:
1. technology and other important assets that can be moved will have already been moved by the US and its allies
2. the rest will be destroyed so that it doesn't fall in the hands of the CCP

There is zero chance that they'll allow China to take control of the facilities, important staff and tech.
 
Of course, everything in the end comes down to one thing, Costs. As TSMC said expect to pay 20% to 30% more when chips are manufactured in the U.S.
IMO, the race to the bottom of the barrel of cost is a sickness that the world has gotten itself into and is totally unsustainable. I'd happily pay 20 to 30-percent more if it goes to supporting US jobs and US semiconductor manufacturing / component manufacturing.

when people complain about small gas price changes... you will see people complain about 20-30% for other things.

nobody is actually supporting home production, it's all talk. it's expensive and it doesn't even guarantee better products.

isn't the point, not inherently. The point is to mitigate TSMC Taiwan being a near-single point of failure.

Like I said, it's all talk. The vast VAST majority of the production is still outsourced.

It's odd to characterize billions and billions of dollars in construction of new fabs as "all talk", but you do you.

Obviously the vast majority of the production is still outsourced, primarily to TSMC, because these fabs aren't finished being built yet. That's the whole point actually building fabs outside of Taiwan, so that production demand can be met without Taiwan.

Can you describe a different path to mitigating reliance on Taiwan for semiconductors, other than building fabs that aren't in Taiwan?

Because I can do it based on where you buy your CPU and GPU. Other than Intel's fabs you have pretty much nothing on the bleeding edge with any kind of real volume production. And even Intel has to outsource...

Just repeating the same non-sequitur statements doesn't make them true. I presented evidence that there are thirteen fabs actively being constructed in America with another nine to be built over the next dozen years - and those nine are just part of one project. Of course they aren't instantly functional and pumping out IC's, they are about the most complex industrial builds humans create, and they take years to build. But it seems your argument is that since those fabs aren't pumping out IC's RIGHT NOW, they are worthless, and just "talk", so why bother building them.

Strange 'logic'.
