fp: Why would using Si28 result in less defects? It wouldn't. The chemical properties of isotopes are identical. The lattice structure is identical. Only the dynamics (phonons etc.) differ and these effects are completely negligible in the wafer processing stage. As I read it, the "ISON seemed to indicate using Si28 would pay for itself in productivity" refers to the increased operating frequency that the parts would be able to attain. Paying $10 a chip for a 30degC temperature decrease (or whatever Isonics claimed that a major chip manufacturer had measured for their 1GHz part - sorry, couldn't find the source) is minimal. And that $10 is for bulk 28Si wafers. Isonics claim that epitaxially grown wafers would only add $0.10 - $1 per chip. -fyo
