TSMC joins giant fab race
Taiwanese contract fab TSMC has become the latest chip-maker to join the 450mm (18 inch) wafer push, announcing a five-year project to put between $US8 billion and $US10 billion into a new chip plant. The project received government approval on Monday. Larger wafers are seen as key to future chip fabrication processes. As chips …

Single crystals
I think these wafers are sliced from single crystals. The crystals for these wafers will be truly enormous.
Re: Single crystals
Well considering even for 300mm the ingots weigh as much as a car probably a safe assumption.
Re: Single crystals
Oops the ones I saw in several companies lobbies sure look like they weighed more but I guess the 300mm average is about that of a decent size street motorcycle. The 450mm ingots will weight a ton or more.
barking up wrong tree
You don't ask Intel or TSMC when we will have 450mm fabs you ask AMAT and the other tool makers. From what I recall the tool makers at first took a bath on the transition to 300mm with the ROI taking years to recover. In a deep recession with chips ever becoming more of a commodity my guess is they will not be in a rush to move to 450mm as they are largely the ones on the hook for getting everything working right.
Re: barking up wrong tree
yes the machine makers are the ones who have to develop the technology. applied materials, telcor etc...it's also why you dont have much proprietary technology on each chip for fabrication. In order to have exclusive technology you have to pay for your own machines development and mfg.
