Research & Development

SP3 Diamond Technologies is the market leader in wide-area diamond deposition, thanks to our proprietary hot-filament chemical vapor deposition (CVD) technology, which enables growth of thin-film, wafer scale diamond coatings on a wide variety of substrate materials. While continued expertise in depositing and growing diamond onto substrates will always be part of our mission, SP3’s over-arching goal is enabling BEST OF BREED DIAMOND COATED PRODUCTS for our customers. So our technical core competencies and R&D efforts goes well beyond CVD diamond deposition. Some of our R&D efforts include:

  • Substrate materials analysis
  • Advanced substrate processes
  • Diamond to substrate adhesion research
  • Cutting tool edge preparation techniques
  • Diamond on silicon
  • Diamond on glass
  • BDD electrodes

SP3 Diamond Technologies utilizes is proprietary Hot-filament CVD (HFCVD) systems to coat substrates with polycrystalline diamond. There are a number of factors that determine whether a substrate material is suitable for CVD diamond coatings. Those materials that are excellent for HFCVD coating are:

  • Silicon carbide
  • Silicon
  • Tungsten carbide
  • Silicon nitride
  • Silicon dioxide
  • Diamond
  • Titanium
  • Niobium
  • Tungsten
  • Molybdenum

Materials that can be coated in certain cases are:

  • Quartz
  • Gallium Nitride
  • Graphite
  • Copper
  • Specialty Glass
