This is the wildest machine you’ve never heard of and it powers all of AI. Here’s a crazy question: how do we print billions of transistors onto a chip when each one is smaller than a grain of dust? The answer is EUV lithography, and it’s absolutely wild. EUV stands for Extreme Ultraviolet lithography. It uses light so tiny, just 13.5 nanometers, that normal mirrors don’t even work. “So where do you even get light that small?” Inside an EUV machine, droplets of molten tin are fired into a vacuum
