Applications of Tungsten Alloy Discs in Target Material Fields

Tungsten alloy discs, with their high density, excellent high-temperature resistance, and corrosion resistance, have wide-ranging applications in the target material field, particularly excelling in advanced manufacturing techniques such as physical vapor deposition (PVD), sputtering coating, and ion beam deposition. As a high-performance target material, tungsten alloy discs play a critical role in industries such as semiconductors, solar cells, display panels, and optical coatings.

In the semiconductor industry, tungsten alloy discs are widely used as sputtering targets to deposit tungsten-based thin films, such as gate electrodes or interconnect layers in transistors. The high melting point and chemical stability of tungsten alloy ensure that the target maintains its performance over long periods in high-vacuum, high-temperature sputtering environments. Its high density guarantees uniform and high-quality thin film deposition. Additionally, the low thermal expansion coefficient of tungsten alloy prevents cracking during rapid temperature changes, making it suitable for high-precision semiconductor processes.

In solar cell manufacturing, tungsten alloy discs serve as targets to deposit conductive or protective layers. For instance, in thin-film solar cells (such as CIGS or CdTe cells), tungsten alloy targets are used to deposit back electrodes or buffer layers. Their excellent conductivity and corrosion resistance ensure the long-term stability and efficient energy conversion of the cells. The high density of tungsten alloy also enhances sputtering efficiency, reducing production costs.

In the production of display panels, tungsten alloy discs are employed to deposit transparent conductive films or metal electrode layers. Their high conductivity and uniform atomic release properties contribute to forming high-quality thin films, improving the conductive performance and optical transparency of display panels. Furthermore, the corrosion resistance of tungsten alloy enables it to adapt to various chemical gases involved in the sputtering process, ensuring target stability and consistency.

In the field of optical coatings, tungsten alloy discs are used to deposit high-reflectivity or anti-reflective coatings, widely applied in optical devices such as lenses, mirrors, and lasers. The high density and high-temperature resistance of tungsten alloy ensure the uniformity and durability of the coatings, while its conductivity and thermal conductivity meet the demands for high-performance coatings in optical devices.
