I don't understand why chip factories don't use 450 mm wafers yet. With 450 mm wafers, they could produce more chips while paying the same wages to factory workers (which are already quite high wages) and even saving some energy and time in manufacturing, which would make the unit cost of each chip lower.
Since new chip factories are going to be built from scratch in the US and Germany, why not build them adapted for 450 mm wafers from the beginning?
In short, with 450 mm wafers, fabs would produce more chips while keeping many of their manufacturing costs the same and other costs would increase only slightly, and thus the cost of producing each chip would be lower.
If 1 chip factory adopts 450 mm wafers, all the others will do the same to have lower manufacturing costs as well.
