The integrated circuit industry develops rapidly and the application scale of precious metals continues to expand.

Because precious metals have good chemical stability, high electrical conductivity, thermal conductivity, and unique electrical, magnetic, optical and other properties, bonding wires, metal evaporation materials, sputtering targets, etc. made of precious metals are widely used. Materials such as surfactants are widely used in the field of integrated circuits. Among them, gold, silver, platinum, ruthenium and…
