Physical vapour deposition
Physical vapour deposition, or PVD, covers vacuum-based techniques including magnetron sputtering, thermal evaporation and e-beam evaporation. The best choice depends on the material, substrate, target film, process atmosphere and required level of configuration.
Plain language guide
What this means in practice
Physical vapour deposition, usually shortened to PVD, is a vacuum method where source material is turned into vapour and then condenses as a film on the substrate. The common research choices are sputtering, thermal evaporation and e-beam evaporation.
What happens in the system
- The chamber is pumped down so gas contamination is reduced and vapour can travel from source to sample.
- The source material is either sputtered by plasma or evaporated by heat or electron-beam heating.
- Atoms or molecules reach the substrate and build a film whose structure depends on rate, pressure, temperature and surface condition.
What changes the result
- PVD methods are often line-of-sight, so sample geometry, source angle and rotation can affect coverage.
- Sputtering and evaporation can both deposit metals, but they stress the material and substrate in different ways.
- Film adhesion is often controlled as much by cleaning, adhesion layers and interface preparation as by the deposition step itself.
Questions to answer first
- Is the source material conductive, insulating, volatile or temperature sensitive?
- Do you need multilayers, co-deposition or a single contact metal?
- Will the process be run by many users who need saved recipes and repeatable setup?

When it helps
Where this technique fits in research workflows
Vacuum deposition processes for creating thin films from a source material onto research substrates. Moorfield can help connect the process requirement to a practical benchtop or modular configuration without treating the guide as a final specification.
Broad material and film-stack exploration
Use PVD as the starting family when you need vacuum deposition of metals, dielectrics, functional coatings or exploratory multilayers.
Local process development
Benchtop PVD can keep early deposition work close to the research group before transfer to larger shared tools.
Configurable source choices
Moorfield can help compare sputtering, evaporation and combined platforms around your material and substrate constraints.

Physical vapour deposition
Physical Vapor Deposition (PVD) is a vacuum deposition method used to produce thin films and coatings. The PVD process involves the transfer of material from a source to a substrate through the vapour phase. This technique is widely used in various industries, including electronics, optics, and material science, to enhance surface properties such as hardness, wear resistance, and corrosion resistance.
Key PVD Techniques:
Magnetron Sputtering
Magnetron sputtering is a form of PVD where ions generated in a plasma are accelerated towards a target material. The impact ejects atoms from the target, which then deposit onto the substrate forming a thin film. This technique is particularly effective for depositing high-melting-point materials and achieving excellent adhesion. Example Applications:
- Semiconductor Industry: Used for depositing metal and dielectric films in integrated circuits.
- Optical Coatings: Applied in manufacturing anti-reflective coatings and decorative films.
- Hard Coatings: Utilised in creating wear-resistant coatings on cutting tools and mechanical components.
Thermal Evaporation
Thermal evaporation is a PVD technique where the material to be deposited is heated to a high temperature until it evaporates. The vapourised atoms then condense on the substrate, forming a thin film. This method is straightforward and suitable for depositing metals and some compounds. Example Applications:
- Metallisation in Electronics: Used for depositing aluminium and other metals on semiconductor wafers.
- Solar Cells: Applied in creating thin metal films in photovoltaic cells.
- Decorative Coatings: Used in the jewellery industry for gold and silver coatings.
Electron-Beam (E-Beam) Evaporation In e-beam evaporation, a focused beam of electrons is directed at the target material, causing it to heat up and evaporate. This technique allows for precise control over the deposition rate and is suitable for materials with very high melting points. Example Applications:
- High-Precision Optics: Used in the deposition of optical coatings for lenses and mirrors.
- Aerospace Components: Applied in coating turbine blades and other high-performance components.
- Research & Development: Used in thin film deposition for new material exploration in laboratories.
PVD processes, including magnetron sputtering, thermal evaporation, and e-beam evaporation, offer versatile solutions for creating high-quality thin films and coatings. Each technique has its unique advantages and is suitable for a range of applications across different industries.
