What is a Silicon Carbide (SiC) Sputtering Target?
Silicon Carbide (SiC) Sputtering Target is a specialized material used in a process called sputtering, which is commonly employed in thin-film deposition for various industries including semiconductor manufacturing, optics, and electronics.
The sputtering target, in this case made of silicon carbide, is a solid material typically in the form of a disc or plate. During sputtering, energetic ions bombard the surface of the target, causing atoms or molecules to be ejected. These ejected particles deposit onto a substrate, forming a thin film.
Silicon carbide sputtering targets are specifically designed to produce thin films composed of silicon carbide, which is a compound of silicon and carbon. The properties of these thin films, such as optical transparency, electrical conductivity, and thermal stability, make them valuable for a wide range of applications, including semiconductor devices, optoelectronics, wear-resistant coatings, and high-temperature components.
