Tharaka, That was not to imply that there is not a wealth of knowledge here on TechNet. Obviously, there is! It is like having a Library of Congress, or some form of World-wide International Technical Library of information at your fingertips I was just attempting to point out additional resources that you may wish to tap into. I was not attempting to promote LinkedIn over TechNet, by any means. I hope that it did not come across that way.

You may also go to LinkedIn, sign up and join one or more of the Semiconductor Processing, or MEMs groups. There are equipment manufacturers there, as well as users. It may be a bit more 'target rich' on the more pure semiconductor related questions. Let me know if I can help you with the LinkedIn stuff. I am by no means an expert, but may be of assistance if there is something which you do not understand, or is not entirely clear.
