What is the advantage of CVD system?

  • Wide range of films can be produced, metal film, nonmetal film and multi-component alloy film as required. At the same time, it can prepare high-quality crystals that are difficult to obtain by other methods, such as GaN, BP, etc.
  • The film forming speed is fast, usually several microns per minute or even hundreds of microns per minute. It is possible to simultaneously deposit large quantities of coatings with uniform composition, which is incomparable to other film preparation methods, such as liquid phase epitaxy (LPE) and molecular beam epitaxy (MBE).
  • The working conditions are carried out under normal pressure or low vacuum conditions, so the coating has good diffraction, and the workpieces with complex shapes can be uniformly coated, which is much superior to PVD.
  • Due to the mutual diffusion of reaction gas, reaction product and substrate, a coating with good adhesion strength can be obtained, which is crucial for preparing surface strengthened films such as wear-resistant and anti-corrosion films.
  • Some films grow at a temperature far lower than the melting point of the film material. Under the condition of low temperature growth, the reaction gas and reactor wall and impurities contained in them almost do not react, so a film with high purity and good crystallinity can be obtained.
  • Chemical vapor deposition can obtain a smooth deposition surface. This is because compared with LPE, chemical vapor deposition (CVD) is carried out under high saturation, with high nucleation rate, high nucleation density, and uniform distribution on the whole plane, resulting in a macroscopic smooth surface. At the same time, in chemical vapor deposition, the average free path of molecules (atoms) is much larger than LPE, so the spatial distribution of molecules is more uniform, which is conducive to the formation of a smooth deposition surface.
  • Low radiation damage, which is a necessary condition for manufacturing metal oxide semiconductors (MOS) and other devices
