It is a high-purity material widely applied to thin film deposition processes and has an important position in magnetron sputtering and physical vapor deposition (PVD) technologies.

1. Characteristics

1) High Purity

Sn targets typically reach a purity of 99.9% or higher and can satisfy applications with high demands on material purity, such as semiconductor and optical plating films.

2) Good electrical conductivity

Sn has excellent electrical conductivity and is suitable for transparent conductive films such as ITO thin film production.

3) Excellent optical performance

Sn film has high transmittance in the visible and infrared bands, making it suitable for optical coatings and anti-reflective films.

4) Chemical stability

Sn is not easily oxidized at room temperature, but can form SnO₂ at high temperatures or in certain environments, making it suitable for the production of specific functional thin films.

5) Customizability

The size, shape, and thickness of Sn targets can be customized according to the needs of the application, such as circular, square, and specially shaped targets.

2. Main Applications

1) Transparent Conductive Oxide(TCO)

Sn targets can be used to produce indium tin oxide (ITO) thin films, which are widely applied to touch screens, liquid crystal displays (LCD) and solar cells.

2) Solar Cells

Sn-based thin films can be used as back electrodes or buffer layers in solar cells to increase photoelectric conversion efficiency.

3) Optical film

Anti-reflective films, infrared reflective films and optical filters are produced and used to enhance the optical performance of lenses and lens.

4) Semiconductor Manufacturing

In integrated circuits (IC) and microelectronic devices, Sn thin films can be used as metallization or barrier layers. 

5) Electromagnetic shielding and wave absorption materials

Recent studies have shown that Sn whisker structures can be used for electromagnetic interference (EMI) shielding and microwave absorption (MA) materials.

6) Decorative and Functional Coatings

For example, low-emissivity (Low-E) coatings on architectural glass and wear-resistant coatings on tools.
