Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
3. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) can be a procedure whereby a substrate is subjected to one or more risky precursors, which react and/or decompose about the substrate surface to create the desired slim movie.
Steps while in the CVD Process:
Precursor introduction
Chemical reaction and film formation
By-products removal
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is yet another spelling usually utilized exterior The usa, especially in British English. Regardless of the spelling variation, it refers back to the same large-precision coating approach.
