Tantalum Target Application

It is welded with copper back target, and then semiconductor or optical sputtering is carried out to deposit tantalum atoms on the substrate material to realize sputtering coating. Tantalum targets are mainly used in semiconductor coating, optical coating and other industries. In the semiconductor industry, metal (Ta) is currently used to form a barrier layer by physical vapor deposition (PVD).



Tantalum Target Alloy Series

In addition to tantalum targets, we can also provide tantalum-silicon alloy, tantalum-aluminum alloy, tantalum-tungsten alloy, nickel-tantalum alloy, cobalt-zirconium-tantalum alloy, tantalum nitride, tantalum carbide, tantalum boride, tantalum pentoxide and other sputtering targets.
