Sputter deposition

Sputter deposition is a technique used to create thin layers of material on a surface. It involves ejecting atoms from a target material using a plasma—an energized state of gas—by bombarding it with ions. These atoms then travel through the vacuum and settle onto a substrate, forming a uniform coating. This process is precise and widely used in manufacturing electronics, solar cells, and coatings, allowing for controlled, high-quality thin films essential for various technological applications.
