I enjoy reading her articles Too bad she's not over here to give her perspective.....and your perspective is at the same level which is really what the thread needs ...I went over to semiconductor online and tried to get someone to talk to me (they have a chat area with no one there)

I wanted to know which companies could solve the testing problem in this paragraph in her article:

Semiconductor Online article
"According to Sheldon, defects are the most serious problem with phase shift masks. No tools are available to inspect masks at the exposure wavelength, so it's very difficult to identify phase defects. The etch process prevents 180ø phase errors, but smaller errors, while less serious, are more difficult to detect. "

AV in his general lithography responded with a slew of companies

Do you concurr on what Sheldon is quoted and AV's chioce He posted another for even more companies.

Thanks in advance

If you haven't already I'll go to Cymer and copy the article there--so its in stone and give a lift to a lousy stock day.And again no Cymer is mentioned at least DPI and ISI are.
Sorry I know its DPI thread may I also ask is PLAB on the same level as DPI??

Again Thanks
