Introduction
Planar Copper (Cu) Sputtering Target is one of the most widely used materials in physical vapor deposition (PVD) processes. Known for its outstanding electrical and thermal conductivity, copper thin films are essential in semiconductor interconnects, microelectronics, photovoltaic devices, and decorative coatings. Planar Cu targets provide stable sputtering performance and high deposition efficiency in both research-scale and large-area industrial coating systems.
Detailed Description
Our Planar Copper Sputtering Targets are manufactured from high-purity copper using vacuum melting, hot working, and precision machining processes to ensure uniform grain structure and minimal impurity levels. Careful control of oxygen and metallic contaminants is critical, as even trace impurities can significantly impact electrical conductivity and film adhesion.
The planar configuration ensures uniform erosion and consistent deposition rates across the substrate surface. High-density targets with homogeneous microstructure reduce arcing and particle generation, enabling stable plasma conditions during DC sputtering. For high-power applications, copper targets can be indium-bonded or diffusion-bonded to copper backing plates to improve heat dissipation and extend target life.
Targets are available in circular, rectangular, and custom planar geometries to match various sputtering cathodes and deposition systems.
