I believe that a lot of people here might be interested in "Minimal Fab", developed by a consortium of Japanese entities. These are kiosk-sized machines that a company can use to set up a fab with a few million dollars. Any individual can then design a chip and have it fabricated very (as in "I want to make a chip for fun") affordably. I was not able to find a ton of information on this, but the 190nm process was supposedly ready last year and there were plans to go below this. The wafers are 12mm in diameter (so basically, one wafer -> one chip) and the clean room is just a small chamber inside the photolithography machine. There are also no masks involved, just direct "drawing".
