ABSTRACT

Contamination control, which has a direct impact on the productivity and profitability of the manufacturing process, is the central concept around which all cleanrooms are designed, built and operated. To help control construction contamination, two methodologies have been used: (1) clean the facility at the end of the construction, called “final super clean”, or (2) continuous cleaning during construction, called “clean-build”. The “clean-build” method is the most widely used contamination control method; however, very little is known about the actual benefit of the “clean-build” approach versus the “final super clean” approach. These two construction methods are compared and some general relationships regarding the use of a particular contamination control method for construction are discussed.
