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 risky precursors, which respond and/or decompose about the substrate surface area to provide the specified slim film.
Steps during the CVD Course of action:
Precursor introduction
Chemical reaction and movie formation
By-item removing
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is yet another spelling normally employed outside The usa, specifically in British English. Regardless of the spelling variation, it refers back to the exact same superior-precision coating approach.
