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 provide the specified slim film.
Actions in the CVD System:
Precursor introduction
Chemical response and film development
By-products elimination
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is an additional spelling normally utilized outside America, specifically in British English. Despite the spelling variation, it refers back to the identical large-precision coating approach.
