Katherine do you have any data that deals with semi equipment lifetimes. There are many different pieces so ther lifespans must vary, also new technology obsoletes older products periodically. The cluster tools of today wiped out many older generations in the 80's, my feeling is the useful life with upgrades is probably around 5 years. Are there any other guesses or data on the subject.
