Sputter Coating - Sputter Deposition

Sputter coating is a physical vapor deposition process used to apply a very thin, functional coating on a substrate. The process starts by electrically charging a sputtering cathode which in turn forms a plasma causing material to be ejected from the target surface. The target material is either bonded or clamped to the cathode and magnets are used to ensure stable and uniform erosion of the material. At a molecular level the target material is directed at the substrate through a momentum transfer process. The high energy target material impacts the substrate and is driven into the surface of the substrate forming a very strong bond at an atomic level. This material is now a permanent part of the substrate rather than an applied coating or plating of the surface.

The real benefits of sputter coating is the stable plasma created which in turn provides a more uniform deposition meaning your coating is consistent and durable. Sputter coating is commonly used in the following coating applications:

- Solar Panels - Architectural Glass - Microelectronics
- Aerospace - Flat Panel Displays - Automotive

Angstrom Science manufactures magnetron sputtering cathodes for a wide range of coating applications. Our magnetrons are custom designed to provide superior magnetic performance and highly efficient thermal conductivity essential in creating a high quality uniform thin film.
