Although designing chips for electronic devices is now easier than ever, making them has never been harder requiring spending vast—and growing—sums on factories (called fabs) stuffed with ultra-advanced equipment.
At the turn of the millennium, a cutting-edge factory might have cost $1bn… More recently, a TSMC factory that produces 3 nm (nanometer) chips, completed in 2020, in southern Taiwan, cost $19.5bn. The firm is already pondering another for factory for 2nm chips, which will almost certainly be more. ..Asia’s nanoscale manufacturing duopoly remains fiercely competitive, as Samsung and TSMC keep each other on their toes… At some point, one company, in all likelihood TSMC, could be the last advanced fab standing. For years, says an industry veteran, tech bosses mostly ignored the problem in the hope it would go away. It has not…
The other big industry rupture is taking place in China. As America has lost ground in making chips, it has sought to ensure that China lags behind, too. The American tech embargo began as a narrow effort against Huawei over national security, but bans and restrictions now affect at least 60 firms, including many involved in chips. SMIC, China’s chip champion, has just been put on a blacklist, as has Xiaomi, a smartphone firm.
