The chip war: why Taiwan, ASML, and export bans decide your tech
One Dutch company makes the machines, one island makes the chips, and the US–China fight over semiconductors reshapes phones, AI, and prices.
The most important machine on earth is the size of a bus, costs several hundred million dollars, and is built by one company in the Netherlands that most people have never heard of. ASML's EUV lithography machines print the microscopic circuits on advanced computer chips, and nobody else on the planet can make one. The chips themselves are manufactured mostly in Taiwan, by TSMC, which produces roughly nine out of ten of the world's most advanced processors on an island that China claims and the United States arms.
Every phone, every car, every AI model, every guided missile depends on this supply chain. Which is why the quiet technical business of making chips has turned into the loudest geopolitical fight of the decade — a struggle the press calls the chip war, fought with export bans instead of bullets.
How did one island end up making everything?
By a decision that looked modest in 1987. A Taiwanese government institute backed an engineer named Morris Chang to start a company with a then-strange business model: make chips only for others, design nothing of your own. Until then, companies like Intel designed and manufactured their chips under one roof. Chang's TSMC let anyone with a design — and eventually that meant Apple, Nvidia, Qualcomm, AMD — rent the world's best factory instead of building one.
The model won so completely that manufacturing consolidated in the winner. Cutting-edge fabrication plants now cost twenty billion dollars and up, take years to build, and demand a decade of accumulated process knowledge. One by one, competitors dropped out of the frontier race; even mighty Intel fell behind. Taiwan calls TSMC its silicon shield — the theory that the world cannot afford to let anything happen to the island because the chips live there. It is either the best insurance policy ever engineered or the most dangerous single point of failure in the world economy, and possibly both.
What did the United States actually do?
Two big moves, in opposite directions. In October 2022, Washington imposed sweeping export controls to keep the most advanced chips and chipmaking tools out of China — including a rule pressuring the Netherlands to withhold ASML's best machines. Nvidia's top AI processors became contraband in the world's second-largest economy, spawning a genuine smuggling trade: chips carried through third countries and resold at markups, seized in raids and reported in cases involving thousands of processors.
The second move was the CHIPS Act, roughly 52 billion dollars to bring manufacturing back to American soil. TSMC is building fabs in Arizona, Samsung in Texas, Intel in Ohio and Arizona. Progress has been real but humbling — the Arizona plants ran into delays, cost overruns, and a shortage of workers with fabrication experience, a reminder that the hard part of chipmaking is not money. It is thirty years of accumulated craft that does not relocate on a subsidy schedule.
Did the export bans work?
Partly, and with a famous backfire. China poured state money into its own champions, and SMIC, its biggest fab, surprised everyone in 2023 by producing a reasonably advanced chip for Huawei phones without the banned machines — older tools pushed cleverly past their design limits. Then in January 2025, the startup DeepSeek trained near-frontier AI models under exactly the constraints the bans imposed, using efficiency to substitute for restricted hardware, and briefly knocked a trillion dollars off the US market's assumptions.
The honest scorecard: the controls slowed China's access to the very top end, raised its costs, and bought time. They also handed Beijing a national mission, taught its engineers to do more with less, and cost American companies billions in lost sales. Both things are true, which is why the policy gets tightened, loosened, and re-argued every few months.
Why should someone who just buys phones care?
Because the chip war sets prices, availability, and risk for everything with a plug. The pandemic gave a preview — a chip shortage idled car factories worldwide and put used-car prices up double digits — and that was caused by mere logistics, not conflict. A real disruption around Taiwan would make that look like a rounding error; estimates of the global cost run into the trillions in the first year.
It is also quietly reshaping the gadgets themselves. The scramble for AI chips decides which companies can build the models in your apps. Export rules decide which countries get which capabilities. And the new fabs rising in Arizona, Japan, and Germany are the world paying an enormous premium for something it used to get cheap: the comfort of not depending on one company, on one island, within reach of one rival, for the brains of modern life.
