Aluminum-Doped Zinc Oxide (AZO) Sputtering Target (ZnO : Al₂O₃ = 98 : 2 wt%)

Description

Aluminum-Doped Zinc Oxide (AZO) Sputtering Targets are high-density ceramic targets composed of 98 wt% Zinc Oxide (ZnO) and 2 wt% Aluminum Oxide (Al₂O₃). By introducing a small amount of aluminum into the ZnO crystal lattice, AZO exhibits significantly enhanced electrical conductivity while maintaining excellent optical transparency across the visible spectrum.

As one of the most widely used Transparent Conductive Oxide (TCO) materials, AZO has become an attractive alternative to Indium Tin Oxide (ITO) due to its lower material cost, excellent chemical stability, environmental friendliness, and the absence of scarce indium. It is widely employed in magnetron sputtering systems for depositing transparent conductive thin films used in displays, photovoltaic devices, optoelectronics, and advanced electronic components.

Tinsan Materials manufactures high-density AZO sputtering targets using carefully selected high-purity raw materials and advanced ceramic processing technology. Each target is engineered to deliver stable sputtering performance, low particle generation, uniform erosion, and high-quality thin-film deposition for both research and industrial production.
