What is Sputtered Deposition?
Sputter deposition is a type of vacuum deposition process that involves the use of a high-energy plasma to “sputter” atoms or molecules from a target material and deposit them onto a substrate. The process takes place in a vacuum chamber, and the target material is typically a solid metal or compound that is placed in a cathode position. The substrate to be coated is placed in an anode position.
During the sputter deposition process, a high-energy plasma is created by applying an electrical current to the cathode. This plasma ionizes the atoms or molecules in the target material and causes them to be ejected from the surface. The sputtered atoms or molecules travel through the vacuum chamber and are deposited onto the substrate, forming a thin film or coating.

Spectrally Selective Component
VDI’s Spectrally Selective component is a highly engineered, multi-layered, film with an optically clear coating that offers superior solar heat rejection, high IR rejection, low visible light rejection and low absorption rate.
Spectrally Selective film provides maximum energy savings with a virtually invisible appearance. VDI’s innovative technology selectively blocks infrared rays while allowing visible sunlight to shine through. Spectrally Selective film is great for maintaining the look of existing glass and is ideal for storefronts, commercial buildings and homes that need minimal light control and excellent heat rejection. The film also reduces passive solar gain even with increased interior illumination levels.Download the Product Sheet
Window Film Component
VDI offers a wide array of component materials that can be used in window film products. From standard metallized aluminum to spectrally selective coatings with different visual appearances and heat rejection properties, VDI can support any window film need. VDI is capable of coating on substrates as thin as 0.5 mil and up to 10 mil.Download the Product Sheet
Sputter deposition is used in a variety of applications, including the production of electronic devices, optics, and decorative coatings. It is a useful technique because it allows for the precise control of the thickness and composition of the deposited film or coating, and it can be used to produce high-quality thin films and coatings. VDI’s capabilities enable it to provide tight tolerances and uniformity of metal deposition, cross web, down-web, and roll-to-roll. In addition, our plasma treatment ensures improved metal adhesion in films.
Sputter deposition is a method of vacuum deposition that can be employed in a roll-to-roll configuration for scalability and efficiency. Sputter deposition is particularly useful for depositing high-quality, uniform thin films with well-controlled composition and thickness.
In the electronics industry, roll-to-roll sputter deposition plays a significant role in the manufacture of flexible displays and photovoltaic materials for solar panels. The method allows for the deposition of high-quality, uniform films on large-area substrates, which is crucial for achieving the high performance and long-term stability required in these applications.
