#375 450 mm? No so fast...

450 mm diameter silicon wafers in production seemed not long ago like a done deal. Well, as it turns out not exactly. It looks like big semiconductor industrial players are one by one postponing/cancelling (for now?) plans to switch to 450 mm platform. What it means is that their bottom line will continue doing ok without going through the very costly transition from 300 mm to 450 mm wafers.


To an old-timer such as myself it is a very interesting, and in the way much telling situation. I follow smooth transitions from one Si wafer size to another since a switch from 4 inch (100 mm) to 5 inch wafer size some 40 years ago and it is for a very first time that the transition is so “bumpy”, extended over long period of time, and overall uncertain. So, long live 300 mm?
