I'm not sure, but I think you could go a long way towards making one chip at a time if you had a supply of virgin wafers and a FIB (focussed ion beam) machine. It allows you to do things like deposit materials, cut them away and do ion implantation without the need for resists, masks, etc. You might still need a separate oven to grow oxide layers, etc. It would be *very* slow going, though. -- Dave Tweed -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
