If you're interested in chip fabrication, I heartily recommend watching https://youtu.be/NGFhc8R_uO4 - it goes over the evolution of how they make transistors all the way up to 2009 state of the art, with a follow up talk in 2013 (https://youtu.be/KL-I3-C-KBk).
Both of them mention how Intel is sinking billions of dollars into ASML to try and get this process working, and how impossible everyone thinks it is, so I'm skeptical that they finally got everything squared away now :)
