Abstract
This paper reviews the historical ultrapure water specifications and compares them to the specifications for state of the art 300 mm manufacturing. As the design rule has evolved to 0.13 µm, the ultrapure water specifications have made similar evolutions. This paper discusses these evolutions and focuses on the state of the art technologies that are available to meet these specifications. Major components in the water system are discussed and their purpose is reviewed. In addition, environmental concerns, operating costs and plant productivity are also discussed. In conclusion, the authors give general considerations and advice on system design.
