Oh, rest assured it is not an error, nor needs correcting, I have recently discussed this subject with Dirk Depta at AMD's Dresden manufacturing facility in Germany and he acknowledged that both companies have collaborated on different levels and have co-developed on 90nm as well, part of that collaboration included the introduction of 300mm wafers and SOI on 200mm.

Collaborated, yes. Worked together on, yes.

But they certainly do not use the same process, as the article assumes. The pressrelease clearly states AMD had already almost finished 90nm development by the time they started working with IBM. Unless you claim AMD threw their own development completely overboard, of course.
I think AMD did some cherry picking from IBM's 90nm technology for their own. There was a $30M something deal involved with that, if I recall. I would assume they picked the best parts - not the troublesome ones.

And you back that all up with a press release that was issued in Januari of 2003? C'mon, think about it for a minute, we're almost two years further now, that press release is pretty outdated. I suggest you contact some of the engineers or people working in R&D at the fab in Dresden to get an accurate perspective of what's actually happening with AMD and IBM's 90nm process. You can rest assured that neither has any time to or desire to re-invent the wheel and there's a huge overlap in technology used, that's one of the benefits of the joint venture. As mentioned the PowerPC processors manufactured by IBM and the Athlons by AMD differ in architecture, but not so much in process technology used to manufacture them. Sure, there are differences, but they are similar enough to validate the claims I make, if you have information or sources indicating otherwise feel free to post them here, with references.

How about AMD's latest roadmaps to back things up? How about some extremely low temps of a system I'm running? And yes, there will be barriers as the process does shrink; this I am aware of. But in the article, the APPLE processor's issues are cited to assume the AMD's will have exactly the same problem. Unless AMD changes their roadmaps, then I can't say they do or do not have problems. I'm mainly trying to point out that the new cores are to be implemented 100% into the lineup, and so far I don't see any problems.

Here's some better proof:

The first one shows a picture of AMD's 90nm process, the second of IBM's. As you can see, there are a few distinct differences between the two.
