Sputter deposition theory

Sputter deposition is a process used to create thin films by ejecting atoms from a solid target material. When a gas is ionized and accelerated toward the target, it collides with its surface, knocking off atoms. These ejected atoms then travel through a vacuum and deposit onto a substrate, forming a thin film. This technique is widely used in electronics, optics, and materials science to produce coatings that enhance surface properties, such as conductivity or durability. The precision and control of sputter deposition make it valuable for creating advanced materials in various technologies.
