High Purity Density Uniformity Al2O3 Aluminum Oxide Sputtering Target

Product Specification

Aluminum oxide targets are made from high-purity aluminum oxide (Al₂O₃) and are commonly used in thin film deposition processes. They are widely applied in vacuum coating, sputtering technology, and other thin film deposition techniques. The properties of aluminum oxide targets include a high melting point, excellent chemical stability, and good thermal conductivity, which collectively ensure stable operation in demanding vacuum coating and sputtering environments. 

Excellent Characteristics of Aluminum Oxide Target (Al₂O₃)

l High Density

Through the application of hot pressing technology, the density of the target is increased to 90–95%, significantly enhancing the material’s strength and stability.

l High Purity

Specially selected raw powder with extremely low impurity levels, ensuring a purity of ≥99.99%.

l High Uniformity

Repeated calibration of sintering parameters ensures uniform temperature control and high material consistency.

 Wide Applications of Aluminum Oxide Target (Al₂O₃)

l Semiconductor Manufacturing

Aluminum oxide targets are widely used in semiconductor manufacturing processes, particularly in integrated circuits and CMOS technology. They are used as insulation layers, high-k dielectric films, and ion implantation masks, offering excellent electrical insulation and thermal stability. Al₂O₃ films can enhance the breakdown voltage and dielectric strength of devices, making them widely used in wafer-level packaging and thin-film capacitors.

l Optical Component Manufacturing

Due to their high transparency, exceptional hardness, and excellent chemical stability, aluminum oxide Al2O3films are ideal for advanced functional optical coatings. Applications include anti-reflection coatings (AR films), infrared filters, and optical protective layers. These coatings ensure that optical systems maintain peak performance in complex environments while effectively improving the wear and corrosion resistance of critical optical components.

l New Energy Applications

Ultrathin aluminum oxide Al₂O₃ films play a vital and versatile role in energy applications. In lithium-ion batteries, the film serves as a protective coating layer. For crystalline silicon photovoltaic cells, it functions as a highly effective surface passivation layer. Within perovskite photovoltaic cells, Al₂O₃ acts as an electron transport layer or a barrier layer to significantly improve overall device performance.

l Display Panels

Aluminum oxide target-produced films have high hardness and strong adhesion, making them ideal for light-transmitting insulation and structural layers. They are used for applications such as anti-scratch coatings for display screens, protective films for precision instruments, and surface hardening treatments for industrial molds. These coatings not only improve wear resistance but also extend the service life of equipment and reduce the maintenance costs.
