Sputtering Considerations

TeO₂ has relatively low thermal conductivity, so appropriate cooling and controlled sputtering power are recommended to minimize localized heating and thermal stress. The deposition rate depends on process parameters such as sputtering power, working pressure, gas composition, substrate temperature, and target-to-substrate distance.

Handling and Storage

Tellurium oxide sputtering targets are securely packaged to minimize the risk of moisture, dust, contamination, and mechanical damage during transportation and storage. Store the targets in a tightly sealed, dry and clean environment, preferably in their original protective packaging, and protect them from moisture and chemical contamination.
