#OpenFabs Ground Up Rebuild [re: secure computer]

Jim Bell and I commented some time ago on this dilemma. One obvious
solution is "table top" manufacture of VLSI.

As crazy as it sounds, for at least prototyping and small (CPunk) PoC
projects, its possible to fab a wide variety of chips, with impressive
feature sizes, implantation, doping, etc. using Electron Beam Lithography.
EBL is basically operating an electron microscope in reverse. Because it
uses electrons to illuminate the substrate vs. photons it doesn't require
any litho masks. The beams can directly write to the surfaces and with the
appropriate techniques expose chemicals that create the "resists" of
typical litho methods. Best of all, electron beams can be brought to a
sharper focus than even deep UV meaning small feature size capabilities.

The main reason EBL is only a tech oddity is its inability to be used for
volume manufacture. Maybe someone in this field will do an ICO. EBL can
potentially be operated by a much smaller staff (maybe a competent enough
individual) than even the smallest conventional fab. With at least small
scale manufacture and some careful design attention I think the list price
on a rig could be < $100k USD.
