Sputtering Targets

Sputtering Targets

Sputtering is a proven technology capable of depositing thin films from a wide variety of materials on to diverse substrate shapes and sizes. The process is repeatable and can be scaled up from small research and development projects, to production batches involving medium to large substrate areas. The sputtering gas is often an inert gas such as argon. For efficient momentum transfer projectile mass must match target mass, so for sputtering light elements neon is also used and for heavy elements krypton or xenon. Reactive gases are used to sputter compounds. The chemical reaction can occur on the target surface, in-flight or on the substrate depending on the process parameters. The many parameters make sputter deposition a complex process but allow experts a large degree of control over the growth and microstructure of the film.

To achieve the desired characteristics in a sputter deposited thin film, the manufacturing process used to fabricate the sputtering target can be critical. Whether the target material comprises only an element, mixture of elements, alloys, or perhaps a compound; the process to produce that defined material in a form suitable for sputtering thin films of consistent quality is as essential as the deposition run parameters perfected by the thin film process engineers and scientists.

SuperVac® Sputtering Targets

Most sputtering target materials can be fabricated into a wide range of shapes and sizes. There are some technical limitations to the maximum size for a given single piece construction. In such cases, a multi-segmented target can be produced with the individual segments joined together by butt or beveled joints. Commonly used targets are circular or rectangular, although other shapes including square and triangular designs can also be produced.

Small Bench Top Coater TargetsRotatable Targets

Testbourne Ltd is proud to announce its new range of rotatable sputtering targets. The rotatable targets are produced by either plasma spraying onto a base tube or from solid pieces. Lengths of over 1000 mm are manufactured.

As a complimentary service to your process Testbourne Ltd provide high quality and competitive Target Bonding to Backing Plates. We can supply backing plates to your specifications whether it is a plain round or rectangular shape plate or a specialized OEM platform design. In many instances, backing plates can be retrieved from spent sputtering target backing plate assemblies. The recovered backing plate is then inspected to ensure it is within specification, cleaned and re-bonded to a new sputtering target.

We also have Silver Epoxy Bonding Kits available in 50g and 100g size packs [...]
