It is older than your phone, older than the company that designed it, older than your country’s investment in semiconductors. Embedded in every modern logic chip is roughly 40 years of accumulated industrial waiting. Mirrors slowly polished in Oberkochen.

In January 2019, a single batch of a specialty chemical called photoresist arrived at TSMC’s Fab 14B in Tainan with something subtly wrong in its molecular structure. By the time engineers noticed, as many as 30,000 silicon wafers had been ruined and the factory had taken a $550 million hit to a single quarter’s revenue. The story is usually filed under supply-chain fragility. It is more accurately a story about time. The dollar figure is the cost when patience fails for ten seconds. The........
