The most expensive factory ever built belongs to the most important tech company you’ve probably never heard of. TSMC of Taiwan uses cutting-edge lasers to etch intricate details less than a thousandth the size of a red blood cell onto the purest hunks of wafer-thin silicon. All while an army of super-strong robots zoom around on tracks traveling the equivalent of ten times around the earth every single day. There’s every chance you already have at least one of its products – integrated circuits, better known as ‘chips’ – in your home or car. But what’s up with the eery yellow lighting inside? Why are they such neat freaks? And could the whole vast enterprise soon be rudely swept away on a rising tide of geopolitical insecurity?
