>>They [IBM] do not want to package any of the die from an ostensibly poorly processed wafer, because they know from experience that they have a higher likelihood of ELF, etc. << Sure, bad processing is bad processing, and yield and reliability are related on individual wafers. But that's not the same as implying, as you did, that an entire fab's output of wafers that passed final test is unreliable. We simply don't have enough information to say whether AMD is also screening out maverick wafers (which would drop their yield in % terms but would actually improve their overall product reliability), or whether their yield problems were due to an automation robot literally dropping wafers (no reliability implications), or what.
