"My reading of Intel (who else!) papers is that there are not enough atoms in a 65 nm structure to be statistically modeled." By the time they do the ring oscillators and the SRAM test vehicles, they have pretty good models. "My feeling is AMD's automated process control tools do not and cannot work at that level," As I understand it, APM doesn't model the devices. It monitors the parameters that are used and the measured results on the test structures. It then keeps a database of tweaks and the results. So when the test structures start giving certain results, it sees what tweaks did what in the past and adjusts the parameters further down the production line to bring the devices on the wafer back to where they want them. "for the reason that whatever experience they have at 90 nm does not apply to 65 nm." It is my understanding that this is true anyway. Each new process has a new learning curve. "I also think 45 nm will be impossible for AMD unless they increase their spending on research to near the level of Intel." And you base this on what, exactly?
