Huygens Optics: DIY Photolithography using 1980s Carl Zeiss S-Planar Lens (405nm)
In this video I demonstrate how I used a Carl Zeiss S-planar wafer stepper lens to do micron-size photolithography and used this pattern to etch a chromium layer. More info on how to etch chromium layers can be found in the second half of the following video: https://www.youtube.com/watch?v=foMT8gLYxBY&t=4s
