Applications of Sputtering Targets;

For film deposition, sputtering targets are employed. A sputtering technique called “deposition made by sputter targets” entails eroding material from a “target” source onto a “substrate” like a silicon wafer.
Targets are etched using semiconductor sputtering targets. When etching anisotropy is required to a great degree and selectivity is not an issue, sputter etching is the method of choice.
By etching away the target material, sputter targets are also utilized for investigation.
In one instance, the target sample is sputtered at a steady pace in secondary ion spectroscopy (SIMS). Using mass spectrometry, the concentration and identity of the spewed atoms are determined when the target is sputtered.

By helping of the sputtering target, the composition of the target material may be evaluated and even extremely tiny amounts of contaminants are recognized.

There is also an application area for sputtering targets in space. One type of space weathering that alters the chemical and physical characteristics of airless worlds like the Moon and asteroids is sputtering.
