摘要

A cleanroom is a pre-constructed isolated, contamination controlled, and actively cleansed space in which scientific research or industrial production occurs. For example, a cleanroom may be used in the industrial production of nanoscale processes, such as for semiconductor manufacturing. A cleanroom may require a low concentration of airborne particles such as dust, airborne organisms, or vaporized particles so as to minimize contamination of the manufactured product.
