They aren't built at the same scale, they're much larger than the final structure and lenses are used to scale the image down to the desired size. Here's a vid

- novaRom 6y agoWow, this explains why production of a mask takes 5 days (as said in first video): https://en.wikipedia.org/wiki/Electron-beam_lithography https://en.wikipedia.org/wiki/Electron-beam_lithography
- jcun4128 6y agoThis was also a cool video I saw recently about lithography with plasma lasers https://www.youtube.com/watch?v=f0gMdGrVteI https://www.youtube.com/watch?v=f0gMdGrVteI around 7:14 in particular
