Useful life of five years sounds about right. A fab (and, by extension, a tool) generally stays on the leading edge for less than a year after it opens. On the other hand, a piece of equipment will remain functional for more like 10 or 15 years, assuming someone has a reason to maintain it. Old equipment often ends up in university labs or making high volume, low technology components like discrete transistors. If I wanted hard data, I'd ask Comdisco. Equipment refurbishing and reselling is their core business. news.semiconductoronline.com Katherine
