Absolutely. I'm doing some research in the background. Try this:

http://www.news.com/A-fab-construction-job/2100-1001_3-981060.html

query: lenses circuits wax Intel
result: MY OWN PAGE *argh* (re: analytical instrumentation)
I also get: "Bryan's page on semiconductor manufacturing" which is also, 
alas, me. But the page contains just as far as I've been able to get so 
far: how to take sand and extract silicon from it, into giant crystals 
that you can pull. The next step is to use diamond saws or diamond wire 
to cut the silicon crystals into the wafers that you start with. The 
diamond wire is very costly: it apparently degrades after a few uses. 
So I haven't been able to figure out how to make my own diamond wire 
yet. Another option might be to use high-powered lasers to cut the 
silicon. Not sure about that one. Then, the next step is to go back 
over Wikibooks book re: photolithography and the chemical etching 
process, which I also have on my /notes.html file on my website. I need 
to flow chart the whole operation soon.

How can we achieve fabbing at home?
- distribute the components across a city, absorb cost
- ship each incremental stage to different members
-- costly packaging, but pricing absorbed by people able to afford each 
individual component of the stage.
