At least some chemicals are from Japan exclusively.
TSMC's wafer manufacturing capacity exceeded 17 million 12-inch equivalent wafers in 2024. -
Statista
A 300 mm wafer yields roughly between 50,000 and 60,000 mm², out of the total 70,700 mm² area.
Power density in logic chips of recent design, the kind that TSMC mostly produces, is around 1 W/mm².
Logic chips made by TSMC alone
each year consume one terawatt of electric power when doing their job, memory/storage/cooling not included. If you're holding out hope for the planet, think of that.
