Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
3. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is really a procedure whereby a substrate is subjected to one or more volatile precursors, which respond and/or decompose about the substrate surface area to supply the desired slender film.
Measures within the CVD Procedure:
Precursor introduction
Chemical response and film formation
By-product or service removing
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is yet another spelling normally employed outside America, notably in British English. Despite the spelling variation, it refers back to the exact same superior-precision coating course of action.
5. CVD and PVD Coating
CVD and PVD coating are both of those Bodily vapor deposition methods employed for making use of slender films. Nonetheless, they differ appreciably within their procedures and programs.
