Understanding Sputtering Targets

Sputtering targets are solid materials made of pure elements, alloys, or compounds that are used as the source material in the sputtering process. During sputtering, high-energy ions bombard the surface of the target material, causing atoms or molecules to be ejected from the target surface. These ejected particles then deposit onto a substrate, forming a thin film with properties determined by the composition of the sputtering target.

Key Applications of Sputtering Targets
