   Trumph makes the gigantic CO2 lasers that nuke the tin droplets.   
      
   It's a very messy, dirty process. Tin splatters everywhere.   
      
   Cymer used flowing hydrogen to capture the tin before it trashed all   
   the optics. GigaPhoton tried to use superconductive magnets somehow,   
   but gave up.   
      
   There must be a better way to do nm lithography. Several people are   
   trying.
