Tungsten Sputtering Target Advantages
- High purity, sintered, and cast tungsten sputtering targets up to 99.95% and beyond.
- Rapid prototyping, powder metallurgy, and direct pressing.
- High density, the density of the tungsten sputtering target after casting can be more than 19.1g/cm3.
- The wide application of the powder metallurgy method makes the cost of tungsten target lower than that of other target materials, such as titanium.
- Uniform composition and structure, improve the deflection force of the tungsten target.
- Fine particle size, grain uniformity, other axes, high concentration, and coating product quality are higher.
Tungsten Sputtering Targets Production Process
Generally prepared by powder metallurgy method, the purity of tungsten powder should be above 99.95%, and the particle size should be between 3.2-4.2 μm. The specific process is as follows:
- Put the tungsten powder in the vacuum heat treatment furnace for pre-gassing, then introduce hydrogen and continue heating for degassing.
- The degassed tungsten powder is sintered once by vacuum hot pressing.
- The primary sintered product is passed through a hot isostatic press to complete the secondary sintering.
- After the secondary sintering, the whole surface of the product is ground by machining to get the final product.
Tungsten Sputtering Target Applications
- Semiconductor Manufacturing: In the manufacture of integrated circuits and microelectronic devices, tungsten sputtering targets are used to deposit conductive or barrier layers by Physical Vapor Deposition (PVD) technology.
- Photovoltaic Industry: Tungsten sputtering targets are used to produce solar panels to form highly efficient photovoltaic conversion layers through sputtering coating, improving the efficiency and stability of solar cells.
- Hard Coatings and Tool Manufacturing: Tungsten’s hardness and wear resistance make it a high-performance coating material. Tungsten sputtering targets are used to produce hard coatings for metal cutting tools, molds, etc. to improve their durability and wear resistance.
- Military and Aerospace: The high density and high strength properties of tungsten sputtering targets make them important in manufacturing military protective equipment and aerospace devices.
- Composants électroniques: The high thermal conductivity and electrical conductivity of the tungsten sputtering target make it play an important role in the heat dissipation material and electromagnetic shielding material of electronic devices.
Tungsten Sputtering Target Packaging
The Tungsten Sputtering Target is carefully placed in wooden cases or cartons, with additional support from soft materials, to prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
