Sputtering targets are key material used to create thin films in a technique known as sputter deposition, or thin film deposition. During this process, sputtering targets begin as a solid and are broken up into tiny particles by gaseous ions, forming a spray and coat another material. Depending on the nature of the thin film being created, sputtering targets have difference in sizes and shapes. The smallest targets can be less than one inch in diameter, while the largest rectangular targets reach well over one yard in length. Sputtering targets are usually circular, many special shapes such as square and triangular can be made upon request, which have greater utility due to the advantages of increased surface area.
Classification
Sputtering targets can be divided into many types according to their geometric shapes, compositions and application fields.
- According to different geometric shapes, sputtering targets can be divided into rectangular (cube) sputtering targets, cylindrical sputtering targets and irregular sputtering targets. In addition, sputtering targets can also be divided into solid sputtering targets and hollow sputtering targets.
- According to different compositions, sputtering targets can be divided into metal sputtering targets, alloy sputtering targets, ceramic compound sputtering targets.
- According to different application fields, sputtering targets can be divided into microelectronic sputtering targets, magnetic recording sputtering targets, optical disc sputtering targets, precious metal sputtering targets, thin film resistance sputtering targets, conductive film sputtering targets, surface modification sputtering targets, mask layer sputtering targets, decorative layer sputtering targets, electrode sputtering targets, packaging sputtering targets, and other sputtering targets.
Applications
Sputtering targets are mainly used in the electronic and information industries, such as flat panel display industry, integrated circuit industry, information storage industry, and optical film industry. They can also be used in industries such as wear resistant materials, high temperature corrosion resistance, chemical plating, metal foam materials and high-grade decorative products. Several typical applications of sputtering targets are listed below.
- Flat panel display industry
In the flat panel display industry, sputtering targets are used in liquid crystal displays (LCD), plasma displays, and field emission displays. At present, the LCD market has the largest demand for sputtering targets, accounting for 80% of the total market demand.
