According to <A HREF="http://www.geek.com/news/geeknews/2002Aug/bch2002082701..." target="_new"> this link</A>, alot of problems that have been associated with moving to the 0.13 process is due to some specific problem involving the copper damascene process. It appears that certian CPU's using this process start to fail after several hundred hours of use. The interesting thing is, I have never seen any real life examples yet, of this problem. It seems so far, to not affect XP's, Tbred's or P4's. The only real life example may be TSMC, but it's still uncertain as to whether they were having this specific problem.

I believe that applies to the graphics card industry. nVidia tried to switch to it for their gf 5, but only had about a 15% or so yield. So nVidia has to now spend millions to convert their .13 factories back to .15.
