Electronic Ultrapure Water
Ultrapure water refers to water that has almost removed all impurities except for hydrogen and oxygen. It spans the manufacturing process of the entire chip. Due to the "cleanliness obsession" of chip production processes, a high yield rate can only be reached by continuous use of large amount of ultrapure water for cleaning. It is estimated that approx 30 liters of ultrapure water are required for a single chip. A well-known factory's ultrapure water even reaches up to 80 million tons per year. Both the stringent water quality standards and astonishing water consumption place extremely high demands on the key equipment RO membrane for producing it. In recent years, VONTRON has broken through technical barriers and successfully developed the UE series ultrapure water membranes, which have been applied in several domestic microelectronics projects.
