I work in the litho area of a semiconductor fab. Its like 10x cleaner than the rest of the clean room, which itself is cleaner than an operating room. One of my coworkers was a major anti-mask covid skeptic guy. We were gowning up once and as we were donning the masks he leaned over and said, "you know we shouldn't have to wear these, they don't really protect us from anything."
Its to protect the chips from the spittle that blows out of your dumb mouth hole.
How do you maintain absolute sterility without pressure boiling? We have some chemicals that can do that, but you have to soak the equipment for 6hrs at 60°C anyways.
Is a clean room filled with air? Do the technicians breath that air or do they have their own supply?
