Did you read the article?
There are 2 cleanrooms. The 2nd story one is undamaged but needs the 1st story one to be repaired (I assume it's a structural thing?). So I'm curious how, from 1 picture, your comment can be informed?
Also from the article, the fire damaged 5% of the first cleanroom and 11 machines. Maybe they're able to get the other 95% back up and running without having the damaged 600sqft fully functional?

I don't believe they have multiple clean floors. Fabs are usually done with space below the clean floor being where machinery for supply of liquids/gasses is, and space above being used for air handling equipment. Some have a storage floor, but that's usually it, especially for a smaller fab.
- newswasboring 6y agoSub fabs are not always about liquids/gases etc. Some fabs, especially bigger DUV fabs, use the sub fab to run their lasers so that scanners can be arranged on the track in a sane way. edit: btw, almost all fabs I have seen have multiple clean floors. Even the sub fabs doing only plumbing work would maintain a clean environment. I'm guessing because thats cheaper than maintaining the interface which goes from clean to unclean environments.
- baybal2 6y agoDo you mean multiple tool floors/litho line floors?
- newswasboring 6y agoTSMC even has litho lines in separate buildings. Its not that uncommon.
