Nope. I haven't reached the end of this. YOU HAVE and you know it. That is why you say "Don't respond" . That is because you know nothing about yields and don't what to wander into this quagmire.
I wrote this awhile back:
And I supplied this quote which you ignored from the Informit:
Lebby indicated on a presentation that they were getting back "extremely high yields on > 1000 poled devices". this is the 97 % end of the range. The answer to why they cannot give away the yields is because the foundries will not allow it as indicated by the quote from the article above.
