The use of PVD materials is a crucial need in an amazing variety of industries. Examples where thin films are used include architectural glass, touch panel displays, solar cells, and architectural glass. Other areas of application include smartphones, bank ATMS, digital photo printers, library information terminals, and car navigation systems. The process used to create these thin layers is known as sputter deposition.
How Sputtering Deposition Works
Sputtering deposition is done in a vacuum chamber. The source used to create the thin material is a called a sputtering target, and it could be made of metal, ceramic or plastic. Air is continually removed in a vacuum, and argon gas is continually introduced to create a low pressure atmosphere. A magnet array behind target creates a magnetic field, and a high voltage is applied to the target. The arc creates a plasma that concentrates along a magnetic field. Within this magnetic field is plasma, argon atoms, argon ions, and free electrons. The argon ions are then attracted to the sputtering target’s surface and chip off the atoms to create the thin film.
At AEM Deposition, we specialize in the creation and production of high purity metals and custom alloys. We have the experience and skills to create affordable, thin material solutions for any need or application. We also have the means to create master alloys and ingots from every metal that exists on the periodic table. Our processes allow us to mill, cut, and grind a vast array of materials, which can be customized to a customer’s needs.
Additional PVD Applications
Additional uses for PVD may include aluminum tracks, ceramic resistors for electronic circuitry, optic coatings, plastic coatings, and coatings to prevent wear for machines and press tools. Thin film applications are extensive and can also be used where anti-fogging, anti-corrosive, stain repellent, non-stick, electrically insulated, low friction, and wear resistant qualities are needed.
PVD materials are amazing elements that affect the daily lives of people in many ways. The process will continue to play a major role in how and why products are created. With the virtual unlimited combination of elements with unique properties, imagining for a whole new world of applications is always possible.
