Rare and precious metal thin films are strategic materials that play a core supporting role in the electronic information industry. Sputtering targets are the key source materials for the preparation of thin films, and are mainly used in the electronics and information industries, such as integrated circuits, information storage, liquid crystal displays, laser memories, electronic control devices, etc.; they can also be used in the field of glass coating; they can also be applied In wear-resistant materials, high temperature corrosion resistance, decorative products and other industries.
​​
At present, the preparation of rare and precious metal targets is mainly concentrated in Japan, the United States, Germany and other countries. The domestic and international gaps are concentrated in the upstream materials of sputtering targets (mainly in terms of pure raw materials) and new products serving the advanced process of integrated circuits.
​​
Through the research and application of new technologies, the main performance indicators of the target product have been achieved. . Among them, the research and development results of nickel-platinum targets in July this year broke the foreign monopoly, enabling similar products to be imported and exported to well-known semiconductor companies in the United States.

It is also understood that the coating target is a sputtering source that forms various functional thin films on the substrate by sputtering by magnetron sputtering, multi-arc ion plating or other types of coating systems under appropriate process conditions. Simply put, the target material is the target material bombarded by high-speed charged particles. It is used in high-energy laser weapons. When lasers with different power densities, different output waveforms, and different wavelengths interact with different targets, they will produce different kills and damages. effect. For example: evaporation magnetron sputtering coating is heating evaporation coating, aluminum film and so on. By replacing different target materials (such as aluminum, copper, stainless steel, titanium, nickel targets, etc.), different film systems (such as superhard, wear-resistant, anti-corrosion alloy films, etc.) can be obtained.
