You have no idea how many steps, robotics, offsets, material feeds, alignments, tool setup, recipe fixing, materials troubleshooting go into a fab. These are all to run automated processes. You underestimate how difficult it is to sink heat in a vacuum and the cost of scaling volume and keeping pressure to a low exponent (high vacuum). Robot surgery is tolerant of a much greater length scale of defect than a modern IC chip and is orders of magnitude fewer process steps. Try to watch a youtube video or something but even then you won’t see the full picture. There are so many layers and the wafer passes through different flavors of the same processes over and over.
