Allan, I'm not a technical guy either, but I think it will all depend on cost and it's still too early predict what will have the cost advantage at those feature sizes. However, Cymer will be selling laser for at least 15 to 20 years and the recent R&D developments in photolithography mean they have plenty of time to work on their post-optical lithography technology. Maybe we can have a more knowledgeable discussion about this in another five years. :-) Bob

Allan, Here's a couple of more tid bits, " So where does all this leave the half-dozen advanced lithography technologies like X-ray and e-beam? MIT's Rothchild questioned whether they would even be needed for semiconductor production now. If lithography ultimately gives out at feature sizes below 0.05 micron, as many researchers expect it to, then a revolutionary new process would have to be developed." It also states that MIT is making it's first 157-nm processing tests using a limited field-of-view stepper that's built in it's own laboratory with a fluoride F2 laser. The laser is operated at 8 watts at a 200-MHz rate. He also noted that calcium fluoride lenses appeared to be more robust than fused silica at 157-nm. Nigel
