Why Semiconductor Factories Cost Billions : Inside the World Most Expensive Buildings

Every time a company announces a new semiconductor factory, the headline almost always includes a staggering price tag. $10 billion. $20 billion. $50 billion. Some projects now stretch beyond $100 billion, making them among the most expensive industrial investments in history. At first glance, it seems impossible that a factory—a building with walls, pipes, and machines—could cost more than airports, skyscrapers, or even entire sports stadiums. But here’s the surprising truth: the building itself isn’t what makes a semiconductor fab so expensive. Most of the money goes into the incredibly advanced machines inside the facility, supported by engineering systems that push the limits of modern science. From extreme ultraviolet (EUV) lithography systems costing hundreds of millions of dollars each to cleanrooms cleaner than hospital operating theaters, every aspect of a chip factory is built with astonishing…
