Hi PeterV. X-ray lithography can be used for .25 and below processing, but it is not commercially feasible for volume production. It is used for limited production military chips. Of the three authors of the article, two are consultants and one is a professor. They may be somewhat removed from the realities of commercial production. However, one of the consultants was formerly with IBM, which is known to have experimented for years with x-ray lithography. The x-ray issue was debated on this thread about one month ago. I'll see if I can find the posts. There's so much daytrading chatter on this thread that it's sometimes hard to find the relevant posts.

Sorry if this has already been replied to, but I figured I would add my 2 cents. 0.25 micron lithography will be done with 248nm (current lasers) 0.18 micron lithography will be done with 248nm and some 193nm 0.15 micron lithography will be done with 193nm (and maybe some strong phase shifted 248nm) 0.13 micron lithgoraphy will be done with 193nm 0.10 micron lithography may be done with 193nm and strong phase shifting and possibly the most likely NGL (next generation lithography candidate, which is not xray). Cymers lasers will be used for all of these generations of lithography as the critical or non-critical layer imaging source. As far as xray and the other NGL's go, SEMATECH and the Semiconductor Industry Association conducted technical review meetings last week and are in the middle of a brainstorming workshop this week. It is apparent from discussions with the attendees that the only certainty is that none of these technologies will be used before the 0.10 micron generation. 248nm and 193nm will be the lithographies of choice by the semiconductor manufacturers down to 0.10 micron. This means that Cymer will support leading edge manufacturing (now) and mainstream manufacturing through ~2010. Hope this helps. TS
