No. You couldn't even buy the cleanroom building for $1m

  You may not need a cleanroom at that feature size today

    Also yield isn't a big concern in a hobby project.

  University labs often have cleanrooms that definitely do cost roughly on the order of low millions. And they are built to the standards of 2010s fabrication requirements. Replicating 1980s cleanroom requirements today would be a lot cheaper. Edit: Page 64 of the pdf https://dokumente.unibw.de/pub/bscw.cgi/d9262701/01_History.pdf https://dokumente.unibw.de/pub/bscw.cgi/d9262701/01_History.... suggests in 1980 the total investment cost of a fab was $100million. I would expect that same tech could be replicated a lot cheaper today. A 100x improvement doesn't seem outrageous.

    I don't see anything on that slight that indicates whether the numbers are inflation-adjusted or not. $100million in 1980 dollars is ~$300million in 2019 dollars. That's going to eat into your savings quite a bit. I'm no expert, but a 100x savings seems pretty outrageous to me and 300x even more so.
