During the sputtering process, atoms are effectively extracted from the sputter target through the use of robust magnets. Meanwhile, a regulated gas, often argon, is introduced into the system. These atoms then interact within their gaseous state, eventually forming a plasma that deposits a thin film onto the substrate.

Many everyday products possess coatings that are manufactured using sputtering materials. Notable examples of these coatings include:

Energy-Efficient Glass Coating

Sputtering targets are instrumental in the production of low-emissivity coated glass (Low-E glass).

Low-E glass is widely utilized in the construction sector for its energy-saving properties, light management, and visual appeal.
