Sputtering (sputter deposition) is a technique of thin film deposition widely used across industries to create thin films of excellent uniformity, density, purity and adhesions over different surfaces. The process involves ejecting atoms from a target or source material which is to be deposited on a substrate.

Sputtering targets (the source of the plating material that is used) are critical in sputter deposition and most sputtering target materials are metallic elements or alloys. Ideally the target should be completely spent after the sputtering process. However, the process is not 100% efficient. On every spent sputtering target, often time there will be valuable metals left unused. Spent sputtering targets can no longer facilitate production and it is expensive and difficult to reclaim the valuable metals.
As most used sputtering targets contain leftover valuable metal, they are worth preserving and recycling. It takes the right metal knowledge and technology to properly handle and process spent sputtering targets to ensure the maximum value is reclaimed. Globe Metal® is a global leader and expert in metal recycling, and we have ample experience in recycling used sputtering targets. We understand the importance and values of rare metals to different industries (e.g. aerospace, semiconductor, display manufacturing, etc.). Thus we ensure the valuable metals remain useful through our recycling programs and only the superior quality minor and primary metals, ferroalloys, high temperature alloys and specialty steels are put back to the economy. Globe Metal® is ISO certified and we provide recycling documentation upon request.
The value of spent sputtering targets varies depending on the value of the metal used as platings, the presence of secondary metals and their quantities. To ensure you are getting the right worth of your used targets, send you materials to a qualified metals recycler like Globe Metal® for testing.

Discover Sputtering Targets from Testbourne
Testbourne is a leading provider of sputtering targets. Sputtering is a technology proven to be capable of depositing thin films from a variety of materials into different shapes and sizes materials. This process can be scaled up to include small research or large manufacturing processes. Discover more about the types of sputtering targets we provide and the different materials available from Testbourne.
Sputtering targets are materials that are used to create thin films in a process called sputter deposition. Sputtering targets are used to produce low-radiation coated glass, used in building construction due to its renewable energy properties, such as saving energy, saving light and for aesthetics.

Our sputtering targets can be produced from a wide range of materials, such as metals and compounds, using processes including rotatable target technology. The choice of material very much depends on the desired properties of the thin film, such as conductivity, renewability, or optical properties.
We offer 3 main types of sputtering targets:
Metal sputtering targets are made from pure metals, such as aluminium, copper, gold, silver, titanium, or metal alloys. Pure metals are most commonly used in the production of electronic devices, such as semi-conductors. Whereas metal alloys are used more commonly in the production of wear-resistant coatings for cutting tools, and biomedical or aerospace components.
At Testbourne our metal targets are offered in various purity levels to suit your specific requirements. Our manufacturing processes for metal sputtering targets depend on the properties of the target metal and its application and thus the fabrication methods we use vary from vacuum melting and rolling, to hot-pressed, vacuum hot-pressed and forged.
Compound sputtering targets are frequently used in industries, including semiconductors, and optical coatings.
The use of compound sputtering targets has several advantages over metal targets, including the ratio of the different elements in the film that can significantly affect its chemical, electrical and optical properties. Also, in comparison to metal sputtering targets, compound targets have a higher durability, so they are more resistant to erosion and cracking.
Testbournes' compound target production methods vary from vacuum hot pressing, hot isostatic pressing, cold isostatic pressing, and cold press sintering, depending on the required metal targets.
Rotatable sputtering targets have a cylindrical shape and are usually made up of metal or ceramic materials. The most common targets are available in chromium, tin, zinc and niobium alloys. Rotatable target technology has been highly used in large area coating manufacturing of architectural glass and flat panel displays. They get their name from the way they rotate during the sputtering process, allowing for a longer target life.
Using rotatable sputtering targets has advantages over other sputtering targets as they allow the use of higher densities because of the even spread of heat build-up over the target surface area. Additionally, they can improve the quality of deposited films, making them a popular choice in industries such as electronics, optics and semiconductors.
