For example, pure water used in power systems, requires low levels of impurities, on the order of "micrograms/liter". In the production of pure water, various indexes specified by a water quality standard are determined according to the production process of electronic (microelectronic) components (or materials) (such as 1/5-1/10 which is generally thought that the size of a particle substance causing circuit performance damage is the line width of the particle substance), but due to the complexity of microelectronic technology and various factors influencing the product quality, a complete water quality standard which is obtained by process tests and is suitable for certain circuit production is not available so far.
