Copper target material

Copper targets are widely used in the vacuum coating industry. Made from high-purity copper processed into specific sizes and shapes, they are applied in electronics, communications, and superconductivity due to their excellent properties. Suitable for DC, RF, ion beam, and magnetron sputtering, Cu targets are used to deposit reflective, conductive, semiconductor, capacitor, decorative, and protective films, as well as for ICs and displays. Compared to other targets, Cu targets are more cost-effective, making them an important material when meeting functional requirements.
