Both DARPA and IBM have been down this path before (several times), without a commercial x-ray product resulting. It's a "cover all bases" strategy, just in case optical techniques do run out of gas (as predicted every two years for the last 10 years). There are several unresolved problems, not the least of which is "where do you get 1 X masks for x-ray at 0.13 microns, when you can't yet get 4 X reticles for this generation. Current commercial mask-making technology only allows features on the mask at about 0.4 microns (minimum dimension). Since you can't buy commercial masks, anyone who uses x-ray will need to open a captive mask shop, at a potential additional cost of $50 million o $100 million. This is NOT going to be a simple "put it in the catalog and sell it" kind of product. Any possible profits from an x-ray stepper are out at least 5 years (as has always been the case). Don't bet on this one too soon. Anyone remember the Bowmar Brain?
