Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
3. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is a process whereby a substrate is exposed to one or more risky precursors, which react and/or decompose within the substrate surface to produce the specified slim film.
Steps during the CVD Course of action:
Precursor introduction
Chemical reaction and movie development
By-solution removing
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is another spelling commonly applied outdoors the United States, significantly in British English. Despite the spelling variation, it refers back to the similar large-precision coating procedure.
