  1. It depends how quickly you can turn a mask layer. If the process is complicated and has to go back through lithography more than a couple times, even not factoring in yield loss from errors this introduces, you can’t justify buying and depreciating the tool for the output of that process. When your EUV scanner costs $150M-$200M, how fast you can pump money out of it is basically all that matters.

  2. There isn’t anything after lithography. There’s only different ways of doing lithography. At the moment the only two technologies that have a chance of equaling high-NA EUV are nanoinprint and DSA. And both of those have unresolved problems with defectivity that have never quite been solved.

  3. “Micron” is standard industry jargon. Which you would know if you worked in this industry.

  4.  @punditgi  I am familiar with metrology. My job is fab metrology. Policing the language of people who actually work in this industry just makes you look like a pedantic dick.
