What it concludes

ASML is the only company in the world that can make EUV lithography machines.
Early X-ray lithography experiments by Hiroo Kinoshita in the 1980s were met with widespread skepticism.
ASML's EUV machines use laser-produced tin plasma inside vacuum chambers to generate 13.5 nm light.
Achieving sufficient power and cleanliness in EUV light sources required decades of engineering and billions in investment from tech companies.
