DC sputtering deposition coating equipment Small PVD machine
Sputtering is a Physical Vapor Deposition vacuum process used to deposit very thin films onto a substrate for a wide variety of commercial and scientific purposes. Sputtering occurs when an ionized gas molecule is used to displace atoms of a specific material. These atoms then bond at the atomic level to a substrate and create a thin film.
In a magnetron sputtering application, the high voltage is delivered across a low pressure gas (usually argon) in order to create high-energy plasma. This plasma emits a colorful halo of light often referred to as a "glow discharge" and consists of electrons (yellow) and gas ions (red).
These energized plasma ions strike a target composed of the desired coating material. The force causes atoms to eject from the target material and bond with those of the substrate.
Because sputtering takes place in a high-energy environment, it creates a virtually unbreakable bond between the film and its substrate at the atomic level, creating one of the thinnest, most uniform, and most cost-effective films possible.
So, given the right tools, researchers and engineers in a variety of industries can use this technique to create a whole new generation of smaller, lighter, more durable products.
