2. What I have to Say…
EUV lithography has been under development for over 20 years
For more than 10 years, promoters of EUVL have been saying the we are “close” to being manufacturing-ready
EUV source developers have promised a 100W source “by the end of the year” (or early next year) every year since 2006
We’re still waiting…
