Making chips at 300mm means more than double the number of working dies per wafer, assuming the same small defect rate, which will allow AMD to help meet demand. Combine that with a transition to a 65nm process node on both their 300mm fabs by the end of next year, and assistance in manufacturing from Chartered Semiconductor, and this $2.5B investment looks well spent. The major upgrade of 30 to 300nm will see it get a name change to Fab38.
AMD are also looking ahead to 45nm wafer production in an agressive timeframe, letting their CPUs get bigger in terms of transistor count for the same overall die space and wafer use, or even smaller with more coming off the boats.
With a stern upcoming challenge to meet from Intel and Core 2 Duo and expectations high on their next generation consumer CPU core -- codenamed K8L -- the transition to larger wafers at 65nm will be a key one for AMD's continued success. The CPU world gets ever more interesting by the day, so keep an eye out to see what both major vendors get up to in the coming months.
Will Fab36, Fab38 and Chartered's capacity be enough on the production side? We'll watch closely and see.
