Applications of Sputtering Targets;

Film deposition is accomplished using sputtering targets. A technique for sputtering thin films is called “deposition made by sputter targets,” which entails eroding material from a “target” source onto a “substrate” like a silicon wafer.
Etching of the target is done using semiconductor sputtering targets. When selectivity is not an issue and a high degree of etching anisotropy is required, sputter etching is the method of choice.
By removing the target material through etching, sputter targets are also utilized for investigation.
In secondary ion spectroscopy (SIMS), one example is when the target material is sputtered at a steady pace. Mass spectrometry is used to quantify the concentration and identity of spewed atoms as 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.
