Ian,
I believe I've heard about ASML having a step and scan system that they are currently selling, and I also believe Canon and Nikon have systems for sale. I have heard Nikon/Canon are having production problems with steppers - I'm not sure if it is particularly with step and scan or with broader DUV stepper issues.
If I remember correctly SVGL optics consist primarily of mirrors, and though I'm not technical in these matters myself, I remember Mr. Akins of Cymer mentioning in his last CC that SVGL machines have certain imaging capabilities with the current lasers that the other vendors can not currently match, due to being primarily lense based.
If we get into particulars, I'm sure SVGL can be put in its own class, but it all depends on what a writer is implicitly referring to with the word "class". If "class" is supposed to mean .25 micron capable step and scan tools in production, I don't think SVGL has this stage all to themselves anymore. I could be wrong, because I don't have proof that other vendors' tools are being used in production environments yet, but it's just a matter of time if so. SVGL does have the lead, and I'm certainly positive on the prospects. It's inevitable that there should be competition in this particular space, and I view $ being spent on development by other companies as proof of the merit/future of step and scan - which SVGL has always used.
It's up to SVGI to execute now with production ramp up. I think it's in their hands whether they grab a chunk of the lithography market or remain a minor player. The payoff would be great, and at this point in stock price, being close to book value makes me comfortable with downside risks. I really have the feeling that I'll look back on this and say if only I'd bought more when it was so low during that Asian scare. We'll see. |
