Redbird,

Re: ISON seemed to indicate using Si28 would pay for itself in productivity. I took this to mean more useful chips per wafer. If so, this would bode well for all chip makers, as it would
reduce their cost per chip.


Why would using Si28 result in less defects? ISON's material has better thermal conductivity, which depends on the nuclear vibrations ... but the electronic properties of the material should be (almost) identical to those of regular Si wafers ... Aren't defects a consequence of chemistry? The chemistry of the ISON Si wafers should not change because you use a nuclear isotope ...
