The art and science of sputtering

In the realm of material science and thin-film deposition, sputtering stands out as a pivotal technique for creating high-quality coatings. Whether you’re developing cutting-edge electronic devices, advanced optics, or high-performance sensors, the choice of sputtering technology can make a significant difference. In this blog post, we will discuss sputtering and explore how  Nikalyte’s NEXUS and NL-FLEX PVD systems are can help you harness the art and science of sputtering.

What is Sputtering?

Sputtering is a physical vapor deposition (PVD) technique used to deposit thin films onto a variety of substrates. It involves ejecting material from a “target” source and depositing it onto a substrate in a vacuum chamber. The process begins when a high-energy plasma bombards the target material, knocking off atoms that then travel through the vacuum and condense on the substrate. [1]

Key benefits of sputtering include:

  • Uniform Coatings: Achieves consistent thin film thickness across complex geometries.
  • Material Versatility: Suitable for a wide range of materials, including metals, oxides, and nitrides.
  • Precise Control: Offers excellent control over film thickness and composition.

Nikalyte’s PVD systems exemplify innovation in sputtering technology through our signature TGC Terminated Gas Condensation Sputtering technique. [2-3]

The TGC process combines sputtering and gas condensation techniques to produce high-quality nanoparticles. In this method, the target material is bombarded by energetic ions, to generate a vapour of metal atoms. This process takes place inside a special chamber called the aggregation zone, which is linked to the main sample chamber by a small aperture. A high pressure (10-1mbar) of argon gas inside the aggregation chamber causes the metal vapour to condenses to form clusters. The clusters grow to form nanoparticles as they travel through the aggregation zone and finally exit into the main sample chamber. The “terminated” aspect refers to controlling the gas environment during the condensation, allowing for enhanced material properties and improved uniformity. This approach is particularly useful in synthesizing complex materials like high-entropy alloys, enabling precise control over composition and microstructure

Our systems are designed to meet the demands of modern research and industrial applications with several standout features.
