Vacuum deposition is a highly versatile and precise process used to deposit thin layers of material onto a substrate in a vacuum or low-pressure environment. This technique is widely employed across industries for applications such as corrosion protection, optical coatings, semiconductor devices, solar cells, and more. The process involves depositing atoms or molecules one at a time, allowing for the creation of extremely thin and uniform layers, often in the nanometer range. Vacuum deposition offers significant advantages, including reduced environmental impact, high precision, and the ability to work with materials that would otherwise oxidize or degrade in atmospheric conditions. This makes it indispensable in modern manufacturing, particularly for advanced technologies like thin-film solar cells, microelectronics, and flexible displays.
