Aurudepositsioon

Aurudepositsioon, also known as vapor deposition, is a general term for a class of thin-film deposition techniques. These methods involve the transfer of material from a gaseous phase onto a solid surface, forming a thin film. The process typically occurs under vacuum or in a controlled atmosphere to ensure purity and directional growth. Aurudepositsioon encompasses a wide range of specific techniques, each with its own advantages and applications.

The fundamental principle behind aurudepositsioon is the creation of a vaporized source material, which then travels to the substrate and condenses to form a solid film. The source material can be vaporized through various methods, such as heating, sputtering, or chemical reactions. The substrate is usually kept at a controlled temperature to influence the film's structure and properties.

Common types of aurudepositsioon include Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). PVD methods involve the physical transfer of atoms or molecules from a source to the substrate, often through processes like evaporation or sputtering. CVD methods, on the other hand, rely on chemical reactions in the gaseous phase to deposit the film. These reactions occur near or on the substrate surface.

Aurudepositsioon is widely used in various industries, including semiconductor manufacturing, optics, and materials science. It is essential for creating protective coatings, conductive layers, optical filters, and microelectronic components. The ability to deposit a wide range of materials with precise control over thickness and composition makes it a versatile and powerful fabrication technique.
