Dale: Additional ML do decrease yield for a given die size, but often shrink the die size enough that even percentage yield increases. For example, K7 was sampled at 5 ML, but produced at 6 ML. The reason for this was that the 5 ML die was 227mm2, while the 6 ML die was only 184mm2. Even with the extra metal layer, percentage yield was higher with the use of a higher number of metal layers.

I did not know that, thanks.
