Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
3. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is actually a approach whereby a substrate is exposed to one or more risky precursors, which react and/or decompose over the substrate area to generate the specified skinny movie.
Techniques from the CVD Approach:
Precursor introduction
Chemical reaction and movie formation
By-item removing
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is another spelling normally utilised outside America, notably in British English. Despite the spelling variation, it refers back to the identical higher-precision coating process.
