High quality pure gold, silver, palladium or platinum round targets

Sputter targets made of high-quality precious metals or their alloys, used in vacuum systems for applying ultra-thin films in applications like Nanolabs' cleanroom coatings.

The sputter targets that IAM Drijfhout supplies consist entirely of precious metals and are used, among other things, in coating and vacuum systems. An example would be the application of thin-films in the cleanrooms of Nanolabs.

Sputtering is a technique involving the application of an extremely thin layer, or ‘thin film’, to a base material (substrate) in a vacuum environment. The so-called target used for sputtering is on one wall of the vacuum chamber and the substrate onto which the sputtered material is applied is on the other. The applied thin layer (thin film coating) can consist of different materials.

The targets are round flat discs that are available in various diameters and thicknesses. They usually consist of pure precious metal or an alloy of precious metal. All precious metals used are of a very high and pure quality: 99.95% or 99.99%.

Precious metals for sputtering targets include:

  • Gold (Au)
  • Gold – palladium, Au/Pd20%
  • Platinum (Pt)
  • Platinum – rhodium; Pt/Rh10%
  • Platinum – palladium Pt/Pd20%
  • Rhodium (Rh)
  • Silver (Ag)

Commonly used sizes and alloys

Usage and application

Thin film coating is a versatile technology used for various applications. From consumer electronics and LED screens to semiconductor lasers, solar cells and medical devices and implants.

A specific example of the use of IAM Drijfhout’s precious metal targets is for: applying thin layers of gold or other precious metals in the production of sensors, semiconductors, batteries and data storage.

The precious metals in sputtering targets can also be extracted for recycling. Given their high purity and the scarcity and expense of the metals involved, recycling sputtering targets can have both economic and environmental motivations.

IAM Drijfhout provides a recycling service for precious metals in all shapes, sizes, and alloys.

As we are also a supplier of precious metal labware we are able to be flexible on arrangements with our clients. For example, whether we pay out the recycling yield or use it as credit for a customer’s new orders.

These gold targets has been used for sputtering and returned for recycling.
