Why does the electronics industry use ultra-pure water equipment?

Ultrapure water plays a more and more important role in the research and production of circuit board-based electronic components. The quality of ultra-pure water has become one of the important factors affecting the product quality, production output and production cost of circuit boards and electronic components. In the production of electronic components, ultra-pure water is mainly used for cleaning water and for the preparation of various solutions and slurries. Different electronic components have different requirements for pure water and water quality.

In the research and production of transistors and integrated circuits, ultrapure water is mainly used to clean silicon wafers, and a small amount is used to prepare chemical liquids, water vapor sources for silicon oxidation, cooling water for some equipment, and preparation of electroplating solutions. 80% of the processes in integrated circuit production require the use of high-purity water to clean silicon wafers. The quality of the water is closely related to the quality and production volume of integrated circuit products. Alkali metals (K, Na, etc.) in the water will cause the insulating film to withstand voltage. Heavy metals (Au, Ag, Cu, etc.) will reduce the PN junction voltage. Group III elements (B, Al, Ga, etc.) will worsen the characteristics of N-type semiconductors. Group V elements ( P, As, Sb, etc.) will worsen the characteristics of P-type semiconductors. The characteristics of P-type semiconductors will deteriorate. If particles (including bacteria) in the water are adsorbed on the surface of the silicon wafer, they will cause a short circuit or deteriorate the characteristics of the circuit.

Ultrapure water equipment is to ensure the quality and safety of electronic products and promote the healthy operation of the electronics industry.
