Zinc Tin Alloy

Zinc Tin Alloy sputtering targets are alloys of zinc and tin used for sputtering coatings. They have a certain thermal and electrical conductivity, are chemically stable at room temperature, and play an important role in the physical vapor deposition process.

Characteristics

Chemical formula: ZnSn

Appearance: metallic color

Hardness: The hardness of the alloy is improved compared to pure zinc and pure tin, which can better withstand ion bombardment and is less likely to produce craters or deformation, thus extending the service life of the target.

Thermal conductivity: It has a certain thermal conductivity, which can effectively conduct the heat generated in the sputtering process, prevent the target from overheating locally, and avoid melting or other physical property changes due to the high temperature of the target.

chemical stability: Good chemical stability at room temperature, but may be chemically reactive in some specific chemical environments, such as strongly acidic or alkaline conditions.

Solubility: it is insoluble in water.

Electrical Characteristics: Its conductivity also varies depending on the ratio of zinc to tin, which affects the plasma characteristics and sputtering rate during sputtering to a certain extent.

Applications

Semiconductor field:

Integrated Circuit Manufacturing: In the manufacturing process of semiconductor chips, it is used to make structures such as wafer conductive layers, barrier layers, and metal gates.
