Titanium nitride (TiN)
Diamond
3. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is usually a approach wherein a substrate is subjected to a number of volatile precursors, which react and/or decompose on the substrate surface area to make the specified thin movie.
Techniques while in the CVD Approach:
Precursor introduction
Chemical reaction and movie formation
By-product removing
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is yet another spelling normally utilised outside America, specially in British English. Despite the spelling variation, it refers back to the identical higher-precision coating process.
