Jeff,
RE:"Line yields - This is perhaps an industry "dirty little secret", but all fabs
do not count zero yield wafers in thier normal yield numbers. Wafers
"zero" with breakage and gross misprocessing. Instead there is a separate
statistic called line yield - the ratio of wafers with some yield to total
wafers processed. Intel has very high line yields. For AMD who knows;
they could be reporting "excellent yields" while throwing away up to half
the wafers under the unreported line yield category."

Thanks, I didn't know that. My edcuation here about chip making hasn't been an easy one because of the blatant hatred of AMD, Intel, NSM etc. getting in the way of sensible posts like yours. I've archived your post with the others that actually gave an unbiased opinion.
As far as the throw away wafers, I'm going to check into that.
Thanks, Jim
