Copper Sputtering Targets
Copper is a ductile metal with very high thermal conductivity, electrical conductivity, ductility, corrosion resistance. A freshly exposed surface of pure copper has a reddish-orange color. High-purity copper is used as various wires in the electronics industry, bonding wires for electronic packaging, high-quality audio cables and integrated circuits, liquid crystal display sputtering targets, and ion plating. It is also an indispensable valuable material in atomic energy, rockets, missiles, aviation, space navigation, and metallurgical industries. AEM can provide high purity OFC, Cupronickel and alloy products as you requested.
AEM Deposition manufacture copper sputtering targets with high purity, the highest purity can reach to 99.9999%. The significant benefits are that your films possess an outstanding level of electrical conductivity and minimized particle formation during the PVD process. The analytical methods we use includes:
1. Metallic elements were analyzed using ICP-OES.
2. Gas elements were analyzed using LECO.
