Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
three. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is often a course of action whereby a substrate is exposed to a number of unstable precursors, which react and/or decompose on the substrate area to make the desired thin movie.
Techniques while in the CVD Method:
Precursor introduction
Chemical reaction and movie formation
By-products elimination
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is yet another spelling frequently utilized outside the house the United States, particularly in British English. Regardless of the spelling variation, it refers to the similar substantial-precision coating procedure.
five. CVD and PVD Coating
CVD and PVD coating are the two Actual physical vapor deposition approaches used for making use of slender films. However, they vary significantly inside their procedures and programs.
CVD (Chemical Vapor Deposition):
