Feature of PVD Tantalum Target:
High melting point,
Low steam pressure,
Good cold working performance,
High chemical stability,
Strong resistance to liquid metal corrosion,
The surface oxide film has a large dielectric constant
Application:
The tantalum target and the copper back target are welded, and then semiconductor or optical sputtering is performed, and the tantalum atoms are deposited on the substrate material in the form of oxides to achieve sputtering coating; tantalum targets are mainly used in semiconductor coating, optical coating and other industries . In the semiconductor industry, metal (Ta) is currently mainly used to coat and form a barrier layer through physical vapor deposition (PVD) as a target material.
We can process according to customer's drawing, and produce Ta rod,plate,wire,foil,crucible etc.
