Sputtering

Sputtering is a process used in manufacturing to create thin, precise coatings on surfaces. It involves bombarding a target material, usually a metal or compound, with high-energy particles like ions. When these particles hit the target, atoms are ejected and then settle onto a nearby surface, forming a thin film. This technique is critical in producing electronics, mirrors, and protective coatings, offering control over thickness and composition. Essentially, sputtering uses energetic particles to transfer material from one surface to another, enabling detailed and durable coatings.
