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 skinny film.
Ways from the CVD Approach:
Precursor introduction
Chemical reaction and movie formation
By-product removing
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is another spelling typically utilized outside the house The us, especially in British English. Regardless of the spelling variation, it refers to the exact same high-precision coating approach.
