Introduction
Zinc Copper (Zn/Cu) Sputtering Targets are alloy targets used for depositing functional thin films where controlled electrical conductivity, optical response, and corrosion behavior are required. By combining zinc’s reactivity and optical characteristics with copper’s excellent electrical conductivity and stability, Zn/Cu alloys enable tailored film properties for electronic, decorative, and functional coating applications.
Detailed Description
Our Zinc Copper Sputtering Targets are manufactured from high-purity zinc and copper through controlled alloying and densification processes to ensure uniform composition and stable sputtering behavior. Precise control of the Zn/Cu ratio is critical, as it directly influences film conductivity, transparency, adhesion, and environmental stability.
Compared with pure zinc targets, the addition of copper improves mechanical strength, reduces target oxidation sensitivity during handling, and enhances film durability. The optimized microstructure and high density help minimize particle generation, arcing, and uneven erosion during sputtering, supporting consistent deposition rates and film quality.
Zn/Cu Sputtering Targets are compatible with DC and RF magnetron sputtering systems, depending on alloy composition and deposition parameters. Targets can be supplied as monolithic pieces or bonded to copper or titanium backing plates to improve heat dissipation and extend target service life in high-power sputtering processes. A wide range of standard and custom sizes is available to match different cathode designs.
Applications
Zinc Copper Sputtering Targets are commonly used in:
Functional and decorative thin-film coatings
Electronic and microelectronic thin films
Optical and reflective coatings
Corrosion-resistant and protective layers
Research and development of alloy thin films
They are particularly suitable for applications requiring balanced conductivity, adhesion, and tunable optical properties.
