Clean Room: the Bedrock of Nanotechnology
Particles even with the smallest sizes can impact advanced material manufacturing and nanotechnology. They mix on the surface of advanced materials and alter the composition and morphology of the material which causes unpredictable results.
A cleanroom is a dust and contamination free environment designed for sensitive processes. The air entering a cleanroom from outside is filtered to exclude dust, and the air inside is continuously recirculated through high-efficiency particulate air filters to remove internally generated contaminants. The inside air pressure is kept positive to prevent unfiltered air from coming in through the room’s leaks.
Some other environmental parameters such as air movement pattern, light, temperature and relative humidity are also kept within specific ranges so that an advanced manufacturing process is performed in a controlled situation. Staff enter a cleanroom wearing protective clothing such as hoods, face masks, gloves, boots, and coveralls.
