Copper Sputtering Target Material:
A sputtering target is a material that is used in the sputtering process, which is a form of physical vapor deposition (PVD). In this process, atoms or molecules are ejected from a solid target material and then deposited onto a substrate, forming a thin film. The sputtering is typically caused by bombarding the target with high-energy ions, usually argon ions.
Copper (Cu) sputtering targets are, therefore, made of copper and are used to deposit thin layers of copper onto various substrates.
Applications:
Copper sputtering targets are used in a range of applications:
- Microelectronics: Copper has become the metal of choice for high-performance silicon integrated circuit interconnections due to its excellent electrical conductivity. Copper thin films are used for metallization in semiconductor devices.
